Quran 8:39 – “And fight with them until there is no more fitna and religion should be only for Allah”
Let’s read a better translation for Q. 8:39,
Pickthall Quran 8:39 And fight them until persecution is no more, and religion is all for Allah. But if they cease, then lo! Allah is Seer of what they do.
The ‘fitna’ mentioned in the above verse (Q 8:39) means persecution, oppression, as shown by Pickthall’s Quran translation. When the verse says, “And fight with them until there is no more fitna”, it gave Muslims permission to fight until there is no more persecution (fitna), 1400 years ago. Critics elude to this passage claiming that the Arabic word ‘fitna’ used here does not really mean ‘persecution’ or ‘oppression’, according to these self-made scholars who have no formal education on Islam, to them the word ‘fitna’ means ‘unbelief’. When it is used in that sense, they’re trying to portray the verse to non-Muslims who don’t know the Arabic language that the passage sanctions Muslims to fight non-believers on account of them of being non-Muslim. However, when we consult Arabic-English dictionaries critics’ deception is exposed. In the following article which can be seen here, I have provided many Muslim and non-Muslim scholarly evidences that the Arabic word ‘fitna’ means, ‘persecution’, ‘oppression’.
Non-Muslim Quran Translations for 8:39
Arthur John Arberry Quran 8:39 Fight them, till there is no persecution and the religion is God’s entirely; then if they give over, surely God sees the things they do…
George Sale Quran 8:39 And fight them until there is no persecution and religion is wholly to God. But if they desist, then surely God is Watchful of what they do.
“39 I.e., until man is free to worship God. Cf. the identical phrase in 2:193, and the corresponding note. Both these passages stress self-defence – in the widest sense of this word – as the only justification of war.” 
The Holy Qur’an Arabic Text With English Translation & Short Commentary – Malik Ghulam Farid:
“1120. Muslims were enjoined to fight till religious persecution had ceased and men were free to practice the religion of their choice. Islam undoubtedly is the greatest upholder of freedom of conscience (2:194).” 
The Holy Quran Arabic Text with English Translation, Commentary and comprehensive Introduction – Maulana Muhammad Ali:
“39a That is, desist from fighting and put an end to their mischief, God’s decree of punishment will not be executed. God sees what men do, and if they mend their ways, He will not punish them. The state of religious liberty which Islam aimed at is put tersely in the two opening statements – ‘there is no more persecution and all religions are for Allah’.
40a. If they return to fight, then Allah will protect the Muslim community, helping them against their enemy, as He is their Patron and Helper.”

Verse is simple what I do not get why We running around the Bush.
No where is the verse without knowing any context Like enemy of islam want to focus. It Say Disbeliever or One who associate or Non Muslim Rather It say
FIGHT THEM so one should ask who is Than. Let just rely of Quran to explain this.
Verse say Until Their No More and Way of Life is for God Alone.
In other word it says Fight Those who committing FITNA( Oppression ) Until Way of Life is for Allah.
Now People say their Two Condition They Stop Oppression and Way of Life of Allah which is on no doubt Is Islam. But Question is Thus Verse End their NO than it say Fa-INi “BUT IF” Like wa And combine Fitna and DEEN for all alone “BUT” is a Insertion or saying exemption that if those condition are not met still, if they Stop.
They Stop What
They Stop the Oppression aggression than Allah see all that they do.
Here Allah is saying don’t worry about them Allah see all that they do. this simple without context with context its more clear but for those who want to focus on verse itself than your answer is in the verse itself.
And fight them until there is no fitnah and [until] the religion(Way of Life), all of it, is for Allah. BUT IF(Fa Ini) they cease – then indeed, Allah is Seeing of what they do.
Now the verse has two clear command ;-1ST And fight them until there is no fitnah and [until] the religion(Way of Life), all of it, is for Allah
2ND BUT IF(Fa Ini) they cease – then indeed, Allah is Seeing of what they do.
Also In arabic deen means fair, accurate, precise dealing, kama deenu tudaanu you’re dealt the wayyou deal others if you take this meaning than And fight them until there is no fitnah and [until] fair, accurate, precise dealing in other word Justice, all of it, is for Allah.
DEEN Does Not Mean Religion. In anyway Quran Explain Itself go Look at verses in Quran index where DEEN is used and you will know its meant meaning, or if you want to follow satan than its your choice.
I am Going to rewrite My response and Hopefully Delete the First One. It has too many grammatical mistake and does not fit the response.
When People quote This Ayat (signs) of Quran Like Verse 39 of Surah(chapter) 8 The Spoil of War(an-Anfal) . They are truly not the seeker of Truth nor They want to really be Guided or Protect People from Misguidance. Because they Qoute Wrong Translation.
Quran is a Kitab(writing) Mehfooz(protected) which is Revelation in Arabic NOT THE TRANSLATION, Indeed all the Translation are Not Transliteration Anymore But actually Misguidance as They are Word of Men. Many Verses are Opinion what The Person Think Than Honest Translation which Everyone of U.S who is Not Master is Arabic Language Deserve.
These People should Repent to Misguide 100s of Million of People, With their Perverse Work and Not sticking to Translating a Word without their Bias and Understanding.
If a Verse Say:- ,Eat Food , It should Not be Translate as “Eat Pure Stuff” Thats What Translator of Quran has done Translate their Bias , Opinion, and Seduction. Indeed People who raise these Verses May be Ignorant or Hate Islam because what Lies They read. Real Enemy of Islam are These So called Self Proclaim Scholars.
IF YOU READ THE SUBJECT IN CONTEXT, You will have No doubt about what happening and what is the command. But I have seen many Refutals which Points out to how People take the verse OUT OF CONTEXT. But even with Deciding of Verse it self, it Proves The Lie, Treachery and Seduction of Enemy of Islam.
“one who Transgress Against His Lord Knowing is Worst than one who is Ignorant” Woe to these People who have Betray the Religion(madzhab) of God.
Now If you Really Reading This than you Know MADZHAB is a Arabic Word for Religion. DEEN is Not Religion.
Deen is semitic Word Found in Hebrew, Arabic, Aramiac and Other semitic Language. I will Not tell you its roots to confuse you but its Used in Hebrew to Mean “LAW”. In Arabic DEEN is Law. LAW which governs Your all Aspect of Life. The People who say is way of life are in Manifest Error.
People who Put a Filthy accusation over God to decree Injustice should know what God Means and who could be Better than GoD to Explain What Deen Means.
First Chapter of Quran has a Verse which say:- Maliki Yawmi-deen. KING of Period of Deen. As Yawn is Period of Time so it is translated as Day, But still a deviation one should say what God say not what You Understand.
In a Another Verse Quran states :-82:18- And what will explain to thee what the YAwm (means Period of Time) Deen?
Answer :- 82:19 – (It will be) the Day when no Ones self shall have power (to do) anything for another one self, and the Decision, that Day, will be (wholly) with Allah.
So This the Day When Everyone will be Accounted or Judge TO ACCOUNTABILITY BY Its True God, He will JUDGE them A Truth Judgement.
So we can say YamiDeen Means Time of Judgement , Time of Account or Time of Decision by Almighty.
When we Take Meaning of “DEEN” out of This it means, Accountability, Judgement Clearly.
It is Used as to Mean LAW of God Or Judgement of God In Another Aya in Quran “Deenilallahi”
Chapter 24:2 – The woman and the man guilty of adultery or fornication,- flog each of them with a hundred stripes: Let not compassion move you in their case, “LAW” Or “judgement” by Allah, if ye believe in Allah and the Last Day: and let a party of the Believers witness their punishment.
In above Verse Both LAW and Judgement fits the Meaning.
As I said You have Accuse Almighty of something injustice so we take What he Explain us DEEN is “Judgement”
Now Let see what you Qoute Chapter 8:39 – And fight them until there is no fitnah and [until] the religion(DEENU), all of it, is for Allah. And if they cease – then indeed, Allah is Seeing of what they do.
First of All Who is Them if you Reject the context, If you don’t than You have no case God Told in Aya or verse before this Verse to seek for them to repent. But You Qoute This Aya without Context But we will find in This Verse Itself By Will of God who are Them.
It Says Fight Them Until there is no fitnah(another word which has deep meaning or closest is Oppression or Evil Corruption)
FIGHT The One who Committing FITNAH it can be Muslim or Non Muslim But I will be truthful They were Disbeliever as we read the CONTEXT.
Fight the Disbeliever Until their No more Evil Corruption or Persecution or Oppression
Now we come to the Part of Deenu , In Arabic WA is Just Like And, It combine condition as one and also Separate them. In this case it superate them in One sense and combine in Another.
DEEN is “Judgement”
SO;- [until] (DEENU) Judgement or Governance, Law, all of it, is for Allah.
Now If we read:- And fight them until there is no fitnah and JUDGEMENT(DEENU), all for Allah. And if they cease – then indeed, Allah is Seeing of what they do.
Where Does It say FIGHT them Unless they ADOPT MADzhab(religion)?
Thus Verse end her NO, Other Part which Carry on is :- then if they cease – then indeed, Allah is Seeing of what they do.
If they Cease Than Allah is seeing of what they do, in other word No more FIGHTING, You Don’t have to worry about them.
This Last Part is Insertion of Exemption, If know Little Law you know when a Law says “Everyone Pay Speeding Ticket But if They Show Regret Fine is Waive” in This But came and Told them the condition when one could be exempt from fine.
Here If they STOP Fitnah Than No FIGHTING.
So now if you Read :- And fight them until there is no fitnah(oppression) and Judgement/ LAW, all of it, is for Allah. And if they cease – then indeed, Allah is Seeing of what they do.
Now DEEN Includes Judgement and Rule Of Allah and Allah has Ruled in Quran :- And say: “The truth is from your Lord.” Then whosoever wills, let him believe, and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong- doers, etc.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water, etc.) they will be granted water like boiling oil, that will scald their faces. Terrible the drink, and an evil Murtafaqa (dwelling, resting place, etc.)!
I Could have chosen a More Simple Verse but I am not here to feel Guilty and try to please Non Muslim but Try to represent Truth. Truth is DEEN of Allah guarantee the choice to Religion.
STOP THE LIES YOU ARE MISGUIDED DO NOT MISGUIDE MORE AND HAVE SIN GREAT ON YOU
If its truth its from My Lord and if I have made Mistake its My Lust and own Desire. May be all Be guided.
Jazakum Allahu khaira
