Description of Jibril in his original form as seen by the Prophet ﷺ at the Sidrat al-Muntaha
The Messenger of Allah ﷺ saw Gabriel in his true form, and he had six hundred wings. Each wing covered the horizon, and from his wings fell precious stones, pearls, and rubies. Allah knows best about him.
رَأَى رَسُولُ اللهِ ﷺ جِبْرِيلَ فِي صُورَتِهِ وَلَهُ سِتُّ مِائَةِ جَنَاحٍ كُلُّ جَنَاحٍ مِنْهَا قَدْ سَدَّ الْأُفُقَ يَسْقُطُ مِنْ جَنَاحِهِ مِنَ التَّهَاوِيلِ وَالدُّرِّ وَالْيَاقُوتِ مَا اللهُ بِهِ عَلِيمٌ
