He went out to relieve himself. Then I brought water for him and he performed ablution, and wiped over his turban and socks. (Using translation from Abū Dāʾūd 153)
عَنْ وُضُوءِ رَسُولِ اللهِ ﷺ فَقَالَ كَانَ يَخْرُجُ يَقْضِي حَاجَتَهُ فَآتِيهِ بِالْمَاءِ فَيَتَوَضَّأُ وَيَمْسَحُ عَلَى عِمَامَتِهِ وَمُوقَيْهِ وَقَالَ غَيْرُهُ تَمِيمُ بْنُ مُرَّةَ
