How to Perform Ablution - Section 2
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذا لبستم وَإِذا توضأتم فابدؤوا بأيامنكم» . رَوَاهُ أَحْمد وَأَبُو دَاوُد
Abu Huraira reported God’s messenger as saying, “When you put on your clothes and when you perform ablution begin with the right side.” Ahmad and Abu Dawud transmitted it.
