The Book of Pilgrimage
15/49. Chapter:
It is recommended to send the weak among women and others ahead from Al-Muzdalifah to Mina at the end of the night, before it gets crowded, but it is recommended for others to stay there until they have prayed Subh in Al-Muzdalifah
Sahih Muslim
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ، ح وَحَدَّثَنَا عَمْرٌو النَّاقِدُ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ سَالِمِ بْنِ شَوَّالٍ، عَنْ أُمِّ، حَبِيبَةَ قَالَتْ كُنَّا نَفْعَلُهُ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم نُغَلِّسُ مِنْ جَمْعٍ إِلَى مِنًى . وَفِي رِوَايَةِ النَّاقِدِ نُغَلِّسُ مِنْ مُزْدَلِفَةَ .
It is narrated from Umm Habiba: We used to set forth from Muzdalifa to Mina, (very early in the dawn) when it was dark. And in the narration of Naqid (the words are):" We set from Muzdalifa in the darkness (of the dawn)."
