Sahih al-Bukhari 1676
Narrated Salim:
`Abdullah bin `Umar used to send the weak among his family early to Mina. So they used to depart 
from Al-Mash'ar Al-Haram (that is Al-Muzdalifa) at night (when the moon had set) and invoke Allah 
as much as they could, and then they would return (to Mina) before the Imam 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 used to say, "Allah's Messenger (ﷺ) gave the permission to them (weak people) to do so."
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ سَالِمٌ وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ ـ رضى الله عنهما ـ يُقَدِّمُ ضَعَفَةَ أَهْلِهِ، فَيَقِفُونَ عِنْدَ الْمَشْعَرِ الْحَرَامِ بِالْمُزْدَلِفَةِ بِلَيْلٍ، فَيَذْكُرُونَ اللَّهَ مَا بَدَا لَهُمْ، ثُمَّ يَرْجِعُونَ قَبْلَ أَنْ يَقِفَ الإِمَامُ، وَقَبْلَ أَنْ يَدْفَعَ، فَمِنْهُمْ مَنْ يَقْدَمُ مِنًى لِصَلاَةِ الْفَجْرِ، وَمِنْهُمْ مَنْ يَقْدَمُ بَعْدَ ذَلِكَ، فَإِذَا قَدِمُوا رَمَوُا الْجَمْرَةَ، وَكَانَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ يَقُولُ أَرْخَصَ فِي أُولَئِكَ رَسُولُ اللَّهِ صلى الله عليه وسلم‏.‏
