Allah's Messenger (ﷺ) asked Gabriel, "Why don't you visit us more often than you do?" Then the following Holy Verse was revealed (in this respect):-- "And we (angels) descend not but by the order of your Lord. To Him belong what is before us and what is behind us, and what is between those two and your Lord was never forgetful." (19.64)
Sahih al-Bukhari Book 59, Hadith 29
← Previous Hadith `Aisha said that the Prophet (ﷺ) said to her "O `Aisha' This is Gabriel and he sends his (greetings) salutations to you." `Aisha said, "Salutations (Greetings) to him, and Allah's Mercy and Blessings be on him," and addressing the Prophet (ﷺ) she said, "You see what I don't see."
