It is narrated from Hazrat Anas that the Noble Prophet (peace and blessings be upon him) indicated to the one shaving his head to start from here, and the Prophet (peace and blessings be upon him) pointed to his right side.

Hazrat Ibn Abbas (may Allah be pleased with both of them) used to say to the one shaving his head: "Start from the right side."

Hazrat Amr bin Dinar says that the person who cut Hazrat Nafi bin Alqamah’s hair during his governorship informed me; he says that Nafi said to me,“Start from the left side.”I said to him,“I had cut the hair of Hazrat Ibn Abbas (may Allah be pleased with them), and he had instructed me to start from the right side.”He said,“Do as you have been instructed.”
