Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to send the weak members of his household ahead, and they would arrive at Muzdalifah by night and stay near Mash'ar al-Haram, and they would remember Allah according to their ability. Then, before the Imam's stay and return, they would go to (Mina). Some would reach Mina at the time of Fajr prayer, and some after that. When they reached Mina, they would throw the pebbles, and Sayyiduna Abdullah bin Umar used to say that the Messenger of Allah (peace and blessings be upon him) had granted this permission to all these people.
