Mishkat al-Masabih, 401

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.

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذا لبستم وَإِذا توضأتم فابدؤوا بأيامنكم» . رَوَاهُ أَحْمد وَأَبُو دَاوُد
