Arabic (Original)
حَدَّثَنَا حُسَيْنُ بْنُ مُحَمَّدٍ وَخَلَفُ بْنُ الْوَلِيدِ قَالَا حَدَّثَنَا إِسْرَائِيلُ عَنْ سِمَاكٍ عَنْ عِكْرِمَةَ عَنْ ابْنِ عَبَّاسٍ قَالَ مَرَّ رَجُلٌ مِنْ بَنِي سُلَيْمٍ عَلَى نَفَرٍ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يَسُوقُ غَنَمًا لَهُ فَسَلَّمَ عَلَيْهِمْ فَقَالُوا مَا سَلَّمَ عَلَيْكُمْ إِلَّا لِيَتَعَوَّذَ مِنْكُمْ فَعَمَدُوا إِلَيْهِ فَقَتَلُوهُ وَأَخَذُوا غَنَمَهُ فَأَتَوْا بِهَا النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ { يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا ضَرَبْتُمْ فِي سَبِيلِ اللَّهِ فَتَبَيَّنُوا وَلَا تَقُولُوا لِمَنْ أَلْقَى إِلَيْكُمْ السَّلَامَ لَسْتَ مُؤْمِنًا } إِلَى آخِرِ الْآيَةَ.
English Translation
A man from Banu Sulaym passed by a group of the Companions of the Prophet (peace be upon him) while driving his sheep. He greeted them with salam, but they said: 'He only greeted us to seek protection from us.' So they attacked and killed him and took his sheep, then brought them to the Prophet (peace be upon him). Allah the Almighty then revealed: 'O you who believe, when you go forth in the cause of Allah, investigate and do not say to one who gives you the greeting of peace: You are not a believer' — to the end of the verse (4:94).
