حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ قِيلَ لِبَنِي إِسْرَائِيلَ ‏{‏ ادْخُلُوا الْبَابَ سُجَّدًا وَقُولُوا حِطَّةٌ يُغْفَرْ لَكُمْ خَطَايَاكُمْ‏}‏ فَبَدَّلُوا فَدَخَلُوا الْبَابَ يَزْحَفُونَ عَلَى أَسْتَاهِهِمْ وَقَالُوا حَبَّةٌ فِي شَعَرَةٍ"‏ ‏.‏
Translation
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".
