باب مَعْنَى قَوْلِ اللَّهِ عَزَّ وَجَلَّ: {وَلَقَدْ رَآهُ نَزْلَةً أُخْرَى} وَهَلْ رَأَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَبَّهُ لَيْلَةَ الإِسْرَاءِ
Sahih Muslim 175

It is narrated on the authority of Abu Huraira that the (words of Allah):

" And certainly he saw him in another descent" (al-Qur'an, Iiii. 13) imply that he saw Gabriel.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ عَبْدِ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ أَبِي هُرَيْرَةَ، ‏{‏ وَلَقَدْ رَآهُ نَزْلَةً أُخْرَى‏}‏ قَالَ رَأَى جِبْرِيلَ ‏.‏
