Who said the following phrase: "No, by Allah, Allah will never disgrace you. For you maintain ties of kinship, you bear the burden of the weak, you earn for the destitute, you entertain guests, and you help in the calamities of truth," and to whom was it said?

These words were spoken by Khadijah bint Khuwaylid, may Allah be pleased with her, when the Prophet, peace and blessings be upon him, returned to her from the cave of Hira after the revelation descended upon him. The Messenger of Allah, peace and blessings be upon him, returned, his muscles trembling, until he entered upon Khadijah and said: "Wrap me up! Wrap me up!" So they wrapped him up until the fear left him.
