Sahih al-Bukhari 1672
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.‏
