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."
Sahih al-Bukhari Book 59, Hadith 46
