It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: Jibril (peace be upon him) came to the Messenger of Allah (peace and blessings be upon him) and said: "Here is Khadijah, coming with a vessel containing curry, food and drink. When she comes to you, convey to her the greeting of peace from her Lord, and give her the glad tidings of a house in Paradise made of pearl, in which there is no noise and no toil."
