باب فِي ذِكْرِ سِدْرَةِ الْمُنْتَهَى ‏‏
Sahih Muslim 174 a

Al-Shaibini reported to us:

I asked Zirr b. Hubaish about the words of Allah (the Mighty and Great):" So he was (at a distance) of two bows or nearer" (al-Qur'an, Iiii 8). He said: Ibn Mas'ud informed me that, verily, the Messenger of Allah (ﷺ) saw Gabriel and he had six hundred wings.
وَحَدَّثَنِي أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، حَدَّثَنَا عَبَّادٌ، - وَهُوَ ابْنُ الْعَوَّامِ - حَدَّثَنَا الشَّيْبَانِيُّ، قَالَ سَأَلْتُ زِرَّ بْنَ حُبَيْشٍ عَنْ قَوْلِ اللَّهِ، عَزَّ وَجَلَّ ‏{‏ فَكَانَ قَابَ قَوْسَيْنِ أَوْ أَدْنَى‏}‏ قَالَ أَخْبَرَنِي ابْنُ مَسْعُودٍ أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى جِبْرِيلَ لَهُ سِتُّمِائَةِ جَنَاحٍ ‏.‏
