Sahih Muslim 1290b
A'isha (Allah be pleased with her) reported that (hadrat) Sauda was a bulky lady, so she sought permission from Messenger of Allah ﷺ to proceed from Muzdalifa (to Mina) in the (latter part of the) night. He granted her permission. 'A'isha said: I wish I had also sought permission from Messenger of Allah ﷺ as Sauda had. sought permission from him. 'A'isha did not proceed but with the Imam.
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، جَمِيعًا عَنِ الثَّقَفِيِّ، - قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا عَبْدُ الْوَهَّابِ، - حَدَّثَنَا أَيُّوبُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ كَانَتْ سَوْدَةُ امْرَأَةً ضَخْمَةً ثَبِطَةً فَاسْتَأْذَنَتْ رَسُولَ اللَّهِ ﷺ أَنْ تُفِيضَ مِنْ جَمْعٍ بِلَيْلٍ فَأَذِنَ لَهَا فَقَالَتْ عَائِشَةُ فَلَيْتَنِي كُنْتُ اسْتَأْذَنْتُ رَسُولَ اللَّهِ ﷺ كَمَا اسْتَأْذَنَتْهُ سَوْدَةُ وَكَانَتْ عَائِشَةُ لاَ تُفِيضُ إِلاَّ مَعَ الإِمَامِ .
