It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) was asked about Sayyidah Khadijah bint Khuwaylid (may Allah be pleased with her), and he (peace and blessings be upon him) said: "I saw her on the bank of one of the rivers of Paradise, in a house made of pearl, in which there is no idle talk and no toil."
