English translation
1676. Narrated Sālim: 'Abdullāh bin 'Umar رضي الله عنهم used to send the weak among his family early to Mina. So they used to depart from Al-Mash'ar Al-Harām (that is Al-Muzdalifa) at night (when the moon had set) and invoke Allāh عزَّ وجلَّ as much as they could, and then they would return (to Mina) before the Imām had started from Al-Muzdalifa to Mina. So some of them would reach Mina at the time of the Fajr prayer and some of them would come later. When they reached Mina they would throw pebbles on the Jamra (Jamrat-al-'Aqaba). Ibn 'Umar رضي الله عنهم used to say, "Allāh's Messenger ﷺ gave the permission to them (weak people) to do so."
