يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا ضَرَبْتُمْ فِي سَبِيلِ اللَّهِ فَتَبَيَّنُوا وَلَا تَقُولُوا لِمَنْ أَلْقَىٰ إِلَيْكُمُ السَّلَامَ لَسْتَ مُؤْمِنًا تَبْتَغُونَ عَرَضَ الْحَيَاةِ الدُّنْيَا فَعِنْدَ اللَّهِ مَغَانِمُ كَثِيرَةٌ ۚ كَذَٰلِكَ كُنْتُمْ مِنْ قَبْلُ فَمَنَّ اللَّهُ عَلَيْكُمْ فَتَبَيَّنُوا ۚ إِنَّ اللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا
O believers, when you go out on a journey in the way of God, be discreet and do not say to anyone who greets you in peace: "You are not a believer." You desire the gain of earthly life, but there are prizes in plenty with God. You were also like him (an unbeliever) in the past, but God has been gracious to you. So be careful and discreet, for God is aware of what you do.
O you who believe! When you go forth (to war) in God’s cause, investigate with care until the situation becomes fully clear to you, and do not say to anyone who offers you (the greeting of) peace (thereby indicating his being a Muslim), "You are not a believer," seeking the fleeting gains of the present, worldly life; for with God are gains abundant. Even thus (as he now is) were you before (ignorant of faith and what being a Muslim is, and you too entered Islam with a similar word); but God has since then been gracious to you. So investigate with care until the situation becomes fully clear to you. Surely God is fully aware of all that you do.
O you who believe! when you set forth in the cause of Allâh, then make proper investigations (before you dub anyone as a disbeliever), and do not say to him who offers you `Salâm´, (- peace, the Muslim salutation to show himself thereby a Muslim,) `You are not a believer.´ You seek the transitory goods of this life, but Allâh has good things in plenty with Him. You were such (disbelievers) before that (you accepted Islam), but Allâh has conferred His special favour on you, hence do make proper investigations. Surely, Allâh is Well-Aware of what you do.
[Hence,] O you who have attained to faith, when you go forth [to war] in God's cause, use your discernment, and do not - out of a desire for the fleeting gains of this worldly life - say unto anyone who offers you the greeting of peace, "Thou art not a believer": 119 for with God there are gains abundant. You, too, were once in the same condition 120 - but God has been gracious unto you. Use, therefore, your discernment: verily, God is always aware of what you do.
O Ye who believe! when ye march forth in the way of Allah, make things clear and say not unto one who giveth you a salutation: thou art none of a believer, seeking the perishable goods of the life of the world; for with Allah are spoils abundant. Even Thus were ye aforetime, then Allah favoured you. So make things clear; verily Allah is of that which ye work ever Aware.
O People who Believe! When you go forth to fight in holy war, make a proper study, and do not say to the one who greets you, "You are not a Muslim," - you seek the means of this worldly life; so with Allah are the bounties in plenty; you too were like this before, then Allah bestowed His favour on you, therefore you must make a proper study; indeed Allah knows whatever you do.
Degrees of rank from Him, and pardon and mercy, for Allah is Forgiving and Merciful.
You, you those who believed, if you moved in God`s sake, so seek clarification/explanation , and do not say to who threw (offered) the peace/surrender/greeting , you are not a believer, you wish/desire the life the present`s/worldly life`s enjoyable accessories, so at God (are) many winnings/gains/spoils, like that you were from before, so God blessed on you, so seek clarification/explanation, that God was/is with what you make/do expert/experienced.
O believers! When you struggle in the way of Allah, investigate carefully, and do not say to anyone who offers you a salutation: "You are not a believer" in order to seek worldly gain by this. Allah has abundant spoils for you. Remember that you yourselves were in the same condition before, Allah has conferred His favors on you. Therefore, make a thorough investigation before considering someone an unbeliever. Allah is well aware of all your actions.
And whoever kills a believer intentionally, his punishment is hell, abiding therein; and Allah is wroth with him and He has cursed him and prepared for him a grievous chastisement.
Believers, if you march with arms for the cause of God, make sure that you know whom to fight. Do not accuse anyone who claims himself to be a Muslim of disbelief just for worldly gains. There is abundant bounty with God. Before, you were also like them, but God bestowed His favors upon you. Thus, make sure that you know whom to fight. God is Well Aware of what you do.
O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye do.
O you who believe! when you go to war in Allah´s way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world´s life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what you do.
O you who believe! When you go (to fight) in the Cause of Allah, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with Allah. Even as he is now, so were you yourselves before till Allah conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. Allah is Ever Well-Aware of what you do.
O ye who believe! When ye go abroad in the cause of Allah, investigate carefully, and say not to any one who offers you a salutation: "Thou art none of a believer!" Coveting the perishable goods of this life: with Allah are profits and spoils abundant. Even thus were ye yourselves before, till Allah conferred on you His favours: Therefore carefully investigate. For Allah is well aware of all that ye do.
