It is narrated from Sayyidah Aishah (may Allah be pleased with her) that when someone from her family died, the women would gather for it and then disperse, except for her family and close relatives. Then she would order a broth of talbinah to be made; it would be cooked and tharid would be prepared, then she would pour the talbinah over it and say: Eat from it, for I heard the Messenger of Allah (peace and blessings be upon him) say: "Talbinah is a source of strength for the heart of the sick person, and it relieves some of the grief."
