النساۤء — An-Nisa' Ayat 94
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِذَا ضَرَبْتُمْ فِيْ سَبِيْلِ اللّٰهِ فَتَبَيَّنُوْا وَلَا تَقُوْلُوْا لِمَنْ اَلْقٰىٓ اِلَيْكُمُ السَّلٰمَ لَسْتَ مُؤْمِنًاۚ تَبْتَغُوْنَ عَرَضَ الْحَيٰوةِ الدُّنْيَا ۖفَعِنْدَ اللّٰهِ مَغَانِمُ كَثِيْرَةٌ ۗ كَذٰلِكَ كُنْتُمْ مِّنْ قَبْلُ فَمَنَّ اللّٰهُ عَلَيْكُمْ فَتَبَيَّنُوْاۗ اِنَّ اللّٰهَ كَانَ بِمَا تَعْمَلُوْنَ خَبِيْرًا

"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."
