"I poured water for him from a small vessel and he performed a light Wudu'. I said to him: 'The prayer.' He said: 'The prayer is still ahead of you.' When he came to Al-Muzdalifah he prayed Maghrib, then they untied the saddles of their mounts and then he prayed 'Isha'." (Using translation from Nasāʾī 609)  

عَنْ أُسَامَةَ بْنِ زَيْدٍ وَكَانَ النَّبِيُّ ﷺ أَرْدَفَهُ مِنْ عَرَفَةَ فَلَمَّا أَتَى الشِّعْبَ نَزَلَ فَبَالَ وَلَمْ يَقُلْ أَهَرَاقَ الْمَاءَ قَالَ فَصَبَبْتُ عَلَيْهِ مِنْ إِدَاوَةٍ فَتَوَضَّأَ وُضُوءًا خَفِيفًا فَقُلْتُ الصَّلَاةَ فَقَالَ «الصَّلَاةُ أَمَامَكَ فَلَمَّا أَتَى الْمُزْدَلِفَةَ صَلَّى الْمَغْرِبَ ثُمَّ نَزَعُوا رِحَالِهِمْ ثُمَّ صَلَّى الْعِشَاءَ»
