Ibn Abbas reported: A man from the tribe of Sulaym passed by a group of companions of the Messenger of Allah, peace and blessings be upon him, and he had some sheep with him. The man greeted them with peace and they said, “He only offered peace to protect himself.” They attacked him, killed him, and took his sheep. They went to the Prophet with them and Allah Almighty revealed the verse, “O you who have faith, when you go forth in the cause of Allah, do not say to whoever greets you with peace that you are not a believer.” (4:94)

عَنْ ابْنِ عَبَّاسٍ قَالَ مَرَّ رَجُلٌ مِنْ بَنِي سُلَيْمٍ عَلَى نَفَرٍ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَمَعَهُ غَنَمٌ لَهُ فَسَلَّمَ عَلَيْهِمْ قَالُوا مَا سَلَّمَ عَلَيْكُمْ إِلَّا لِيَتَعَوَّذَ مِنْكُمْ فَقَامُوا فَقَتَلُوهُ وَأَخَذُوا غَنَمَهُ فَأَتَوْا بِهَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَنْزَلَ اللَّهُ تَعَالَى يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا ضَرَبْتُمْ فِي سَبِيلِ اللَّهِ فَتَبَيَّنُوا وَلَا تَقُولُوا لِمَنْ أَلْقَى إِلَيْكُمْ السَّلَامَ لَسْتَ مُؤْمِنًا
