question #1 Sahih Muslim 177d, Book 1, Hadith 347 : Who is described as coming to the Prophet Muhammad in his true form according to Islamic teachings?

I said to ‘A’isha: What about the words of Allah:” Then he drew nigh and came down, so he was at a distance of two bows or closer still: so He revealed to His servant what He revealed” (al-Qur’an, liii. 8-10)? She said: It implies Gabriel. He used to come to him (the Holy Prophet) in the shape of men; but he came at this time in his true form and blocked up the horizon of the sky.
