Mukhtasar Muslim (Abridged) 124 — Starting with the right side

‘It is narrated from Umm al-Mu’minin Aisha Siddiqa Tayyiba Tahira (may Allah be pleased with her) that’ indeed, the Messenger of Allah (peace and blessings of Allah be upon him) liked to begin with the right side in purification, combing his hair, and putting on his shoes.
