The Messenger of Allah ﷺ used to love starting from the right whenever possible, in his purification, in putting on his sandals, and in combing his hair.Shuba said, "Then I heard Ashath in Wasit say, 'He loved starting from the right,' and he mentioned the matter in its entirety. Then I heard him in Kufa say, 'He loved starting from the right whenever possible.'"
أخبرنا محمد بن عبد الأعلى قال حدثنا خالد قال حدثنا شعبة قال أخبرني الأشعث قال سمعت أبي يحدث عن مسروق
أن رسول الله ﷺ كان يحب التيامن ما استطاع في طهوره ونعله وترجله قال شعبة ثم سمعت الأشعث بواسط يقول يحب التيامن فذكر شأنه كله ثم سمعته بالكوفة يقول يحب التيامن ما استطاع
