Sunan an-Nasa'i, Book 48, Hadith 201 (In-Book) ⓘ
It was narrated from 'Aishah that: The Messenger of Allah [SAW] liked to start on the right whenever possible; when purifying himself, when putting on his shoes, and when combing his hair.
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي الأَشْعَثُ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، وَذَكَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُحِبُّ التَّيَامُنَ مَا اسْتَطَاعَ فِي طُهُورِهِ وَتَنَعُّلِهِ وَتَرَجُّلِهِ .
