Hazrat Ata (may Allah have mercy on him) narrated that the Messenger of Allah (peace and blessings be upon him) permitted people to depart from Muzdalifah to Mina in the last part of the night. Nafi' (may Allah have mercy on him) narrates that Sayyiduna Ibn Umar (may Allah be pleased with them both) used to send his son, while he was still a child, (from Muzdalifah at night), until he would lead him in the Fajr prayer at Mina.
