Musnad Ahmad 25:1147

Abdullah ibn Yazid narrated to us, al-Mas'udi narrated to us, from al-Hakam, from Miqsam, from Ibn Abbas, that the Messenger of Allah (peace and blessings of Allah be upon him) sent ahead the weak ones of his family from Muzdalifah by night. He began to instruct them not to stone the Jamrat al-Aqabah until the sun had risen.
