Safiyyah bint Atiyyah said: I went in with some women of Abd al-Qays to Sayyidah Aishah (may Allah be pleased with her), and we asked her about dates and raisins. She said: "I used to take a handful of dates and a handful of raisins, put them in a vessel and mash them, then give it to the Prophet (peace and blessings be upon him) to drink."
