Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) sent the weak members of his household off from Muzdalifah while it was still night. Then he came to us one by one, patting us on our thighs, and I was among those whose thigh he (peace and blessings be upon him) patted. Then he said: "O my son, do not stone Jamrat al-Aqabah until the sun rises."
