Sahih al-Bukhari 1678
Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · Whosoever sent the weak amongst his family (women and children) early (from Al-Muzdalifa to Mina) at night after the moon had set. They stayed at Al Muzdalifa and invoked Allah there and proceeded from there when the moon had set
Narrated Ibn `Abbas:
حَدَّثَنَا عَلِيٌّ ، حَدَّثَنَا سُفْيَانُ ، قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ أَبِي يَزِيدَ ، سَمِعَ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ يَقُولُ أَنَا مِمَّنْ ، قَدَّمَ النَّبِيُّ صلى الله عليه وسلم لَيْلَةَ الْمُزْدَلِفَةِ فِي ضَعَفَةِ أَهْلِهِ.
I as among those whom the Prophet (ﷺ) sent on the night of Al-Muzdalifa early being among the weak members of his family.
