Messenger of Allah ﷺ on his way back from 'Arafat got down in one of these creeks (to answer the call of nature), and after he had done that I poured water (over his hands) and said: Are you going to pray? Thereupon he said: The place of prayer is ahead of you.
انْصَرَفَ رَسُولُ اللَّهِ ﷺ بَعْدَ الدَّفْعَةِ مِنْ عَرَفَاتٍ إِلَى بَعْضِ تِلْكَ الشِّعَابِ لِحَاجَتِهِ فَصَبَبْتُ عَلَيْهِ مِنَ الْمَاءِ فَقُلْتُ أَتُصَلِّي فَقَالَ الْمُصَلَّى أَمَامَكَ
