Chapter: The marriage of the Prophet (saws) with Khadija رضي الله عنها and her superiority
Narrated 'Aisha:
Once Hala bint Khuwailid, Khadija's sister, asked the permission of the Prophet (ﷺ) to enter. On that, the Prophet (ﷺ) remembered the way Khadija used to ask permission, and that upset him. He said, "O Allah! Hala!" So I became jealous and said, "What makes you remember an old woman amongst the old women of Quraish an old woman (with a teethless mouth) of red gums who died long ago, and in whose place Allah has given you somebody better than her?"
