Sahih Muslim , Hadith 3025 ⓘ
Ibn Abbas reported that some Muslims met a person with a small flock of sheep. He said: As-Salam-o-'Alaikum. They caught hold of him and killed him and took possession of his flock. Then this verse was revealed:" He who meets you and extends you salutations, don't say: You are not a Muslim" (iv. 94). Ibn 'Abbas, however, recited the word as-Salam instead of" as-Salam".
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَأَحْمَدُ بْنُ عَبْدَةَ الضَّبِّيُّ، - وَاللَّفْظُ لاِبْنِ أَبِي شَيْبَةَ - قَالَ حَدَّثَنَا وَقَالَ الآخَرَانِ، أَخْبَرَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَقِيَ نَاسٌ مِنَ الْمُسْلِمِينَ رَجُلاً فِي غُنَيْمَةٍ لَهُ فَقَالَ السَّلاَمُ عَلَيْكُمْ . فَأَخَذُوهُ فَقَتَلُوهُ وَأَخَذُوا تِلْكَ الْغُنَيْمَةَ فَنَزَلَتْ { وَلاَ تَقُولُوا لِمَنْ أَلْقَى إِلَيْكُمُ السَّلَمَ لَسْتَ مُؤْمِنًا} وَقَرَأَهَا ابْنُ عَبَّاسٍ السَّلاَمَ .
