Yusuf Ali
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.

Sahih International
O you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted.

Shakir
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.

Pickthall
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.

محمد جالندھری
مومنو! جب تم خدا کی راہ میں باہر نکلو کرو تو تحقیق سے کام لیا کرو اور جو شخص تم سے سلام علیک کرے اس سے یہ نہ کہو کہ تم مومن نہیں اور اس سے تمہاری غرض یہ ہو کہ دنیا کی زندگی کا فائدہ حاصل کرو سو خدا کے نزدیک بہت سے غنیمتیں ہیں تم بھی تو پہلے ایسے ہی تھے پھر خدا نے تم پر احسان کیا تو (آئندہ) تحقیق کرلیا کرو اور جو عمل تم کرتے ہو خدا کو سب کی خبر ہے
