Messenger of Allah ﷺ proceeded from ʿArafat and dismounted at the mountainous pass and then urinated and performed a light ablution. I said to him, "(Shall we offer) the prayer?" He replied, "The prayer is ahead of you (i.e. at Al-Muzdalifa)." When he came to Al-Muzdalifa, he performed a perfect ablution. Then Iqama for the prayer was pronounced and he offered the Maghrib prayer and then every person made his camel kneel at his place; and then Iqama for the prayer was pronounced and he offered the (ʿIsha') prayer and he did not offer any prayer in between them (i.e. Maghrib and ʿIsha' prayers).
أَنَّهُ سَمِعَهُ يَقُولُ دَفَعَ رَسُولُ اللَّهِ ﷺ مِنْ عَرَفَةَ فَنَزَلَ الشِّعْبَ فَبَالَ ثُمَّ تَوَضَّأَ وَلَمْ يُسْبِغِ الْوُضُوءَ فَقُلْتُ لَهُ الصَّلاَةُ فَقَالَ الصَّلاَةُ أَمَامَكَ فَجَاءَ الْمُزْدَلِفَةَ فَتَوَضَّأَ فَأَسْبَغَ ثُمَّ أُقِيمَتِ الصَّلاَةُ فَصَلَّى الْمَغْرِبَ ثُمَّ أَنَاخَ كُلُّ إِنْسَانٍ بَعِيرَهُ فِي مَنْزِلِهِ ثُمَّ أُقِيمَتِ الصَّلاَةُ فَصَلَّى وَلَمْ يُصَلِّ بَيْنَهُمَا
