Narrated Masruq:
حَدَّثَنِي مُحَمَّدُ بْنُ يُوسُفَ ، حَدَّثَنَا أَبُو أُسَامَةَ ، حَدَّثَنَا زَكَرِيَّاءُ بْنُ أَبِي زَائِدَةَ ، عَنِ ابْنِ الأَشْوَعِ ، عَنِ الشَّعْبِيِّ ، عَنْ مَسْرُوقٍ ، قَالَ قُلْتُ لِعَائِشَةَ ـ رضى الله عنها ـ فَأَيْنَ قَوْلُهُ {ثُمَّ دَنَا فَتَدَلَّى * فَكَانَ قَابَ قَوْسَيْنِ أَوْ أَدْنَى} قَالَتْ ذَاكَ جِبْرِيلُ كَانَ يَأْتِيهِ فِي صُورَةِ الرَّجُلِ، وَإِنَّهُ أَتَاهُ هَذِهِ الْمَرَّةَ فِي صُورَتِهِ الَّتِي هِيَ صُورَتُهُ، فَسَدَّ الأُفُقَ.
I asked Aisha "What about His Statement:-- "Then he (Gabriel) approached And came closer, And was at a distance Of but two bow-lengths Or (even) nearer?" (53.8-9) She replied, "It was Gabriel who used to come to the Prophet (ﷺ) in the figure of a man, but on that occasion, he came in his actual and real figure and (he was so huge) that he covered the whole horizon."
