Narrated Usama bin Zaid:Allah's Messenger (ﷺ) proceeded from `Arafat 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 (`Isha') prayer and he did not offer any prayer in between them (i.e. Maghrib and `Isha' prayers).
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، عَنْ أُسَامَةَ بْنِ زَيْدٍ ـ رضى الله عنهما ـ أَنَّهُ سَمِعَهُ يَقُولُ دَفَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم 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.
