17:93 Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my lord; am I aught but a mortal apostle?
Holy Quran 53
ذُو مِرَّةٍ فَاسْتَوَىٰ
One free from any defect in body and mind then he (Jibril - Gabriel in his real shape as created by Allah) rose and became stable.
وَهُوَ بِالْأُفُقِ الْأَعْلَىٰ
While he [Jibril (Gabriel)] was in the highest part of the horizon, (Tafsir Ibn Kathir)
ثُمَّ دَنَا فَتَدَلَّىٰ
Then he [Jibril (Gabriel)] approached and came closer,
فَكَانَ قَابَ قَوْسَيْنِ أَوْ أَدْنَىٰ
And was at a distance of two bows' length or (even) nearer.
فَأَوْحَىٰ إِلَىٰ عَبْدِهِ مَا أَوْحَىٰ
So (Allah) revealed to His slave [Muhammad صلى الله عليه وسلم through Jibril (Gabriel) عليه السلام] whatever He revealed.
