باب اسْتِحْبَابِ تَقْدِيمِ دَفْعِ الضَّعَفَةِ مِنَ النِّسَاءِ وَغَيْرِهِنَّ مِنْ مُزْدَلِفَةَ إِلَى مِنًى فِي أَوَاخِرِ اللَّيَالِي قَبْلَ زَحْمَةِ النَّاسِ وَاسْتِحْبَابِ الْمُكْثِ لِغَيْرِهِمْ حَتَّى يُصَلُّوا الصُّبْحَ بِمُزْدَلِفَةَ
Sahih Muslim 1291 a

Abdullah, the freed slave of (Hadrat) Asma', reported:

Asma' (Allah be pleased with her), as she was in the house at Muzdalifa, asked me whether the moon had set. I said: No. She prayed for some time, and again said: My son has the moon set? I said: Yes. And she said: Set forth along with me, and so we set forth until (we reached Mini) and the stoned at al-Jamra. She then prayed in her place. I said to her: Respected lady, we set forth (in the very early part of dawn) when it was dark, whereupon she said: My son, there is no harm in it; Allah's Apostle (ﷺ) had granted permission to women.
حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ الْمُقَدَّمِيُّ، حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنِ ابْنِ جُرَيْجٍ، حَدَّثَنِي عَبْدُ اللَّهِ، مَوْلَى أَسْمَاءَ قَالَ قَالَتْ لِي أَسْمَاءُ وَهْىَ عِنْدَ دَارِ الْمُزْدَلِفَةِ هَلْ غَابَ الْقَمَرُ قُلْتُ لاَ ‏.‏ فَصَلَّتْ سَاعَةً ثُمَّ قَالَتْ يَا بُنَىَّ هَلْ غَابَ الْقَمَرُ قُلْتُ نَعَمْ ‏.‏ قَالَتِ ارْحَلْ بِي ‏.‏ فَارْتَحَلْنَا حَتَّى رَمَتِ الْجَمْرَةَ ثُمَّ صَلَّتْ فِي مَنْزِلِهَا فَقُلْتُ لَهَا أَىْ هَنْتَاهْ لَقَدْ غَلَّسْنَا ‏.‏ قَالَتْ كَلاَّ أَىْ بُنَىَّ إِنَّ النَّبِيَّ صلى الله عليه وسلم أَذِنَ لِلظُّعُنِ ‏.‏
