(77) باب مَعْنَى قَوْلِ اللَّهِ عَزَّ وَجَلَّ: {وَلَقَدْ رَآهُ نَزْلَةً أُخْرَى} وَهَلْ رَأَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَبَّهُ لَيْلَةَ الإِسْرَاءِ
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.
