Sayyiduna Abu Rafi' (may Allah be pleased with him) said: When Sayyidah Fatimah (may Allah be pleased with her) gave birth to Hasan (may Allah be pleased with him), she said: O Messenger of Allah, shall I not perform the aqiqah for my son? He (peace and blessings be upon him) said: "No, but shave his head and give in charity to the poor silver coins equal to the weight of his hair - or he said: silver." When she gave birth to Sayyiduna Husayn (may Allah be pleased with him), she did the same for him. Musa bin Dawud said in his narration: "To the homeless travellers and the poor."
