Funerals (Al-Janaa'iz)
Chapter: Who may get down in the grave of a woman
Narrated Anas:
We were in the funeral procession of the daughter of Allah's Messenger (ﷺ) and Allah's Messenger (ﷺ) was sitting near the grave and I saw his eyes full of tears. He said, "Is there anyone amongst you who did not have sexual relations with his wife last night?" Abu Talha replied in the affirmative. And so Allah's Apostle told him to get down in her grave and he got down in her grave and buried her.
