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 `Aisha:
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ ، أَخْبَرَنَا سُفْيَانُ ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ ـ هُوَ ابْنُ الْقَاسِمِ ـ عَنِ الْقَاسِمِ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتِ اسْتَأْذَنَتْ سَوْدَةُ النَّبِيَّ صلى الله عليه وسلم لَيْلَةَ جَمْعٍ وَكَانَتْ ثَقِيلَةً ثَبْطَةً فَأَذِنَ لَهَا.
Sauda asked the permission of the Prophet (ﷺ) to leave earlier at the night of Jam', and she was a fat and very slow woman. The Prophet (ﷺ) gave her permission.
