Sayyida Umm al-Husayn (may Allah be pleased with her) narrated that I heard the Messenger of Allah (peace and blessings be upon him) say: He (peace be upon him) supplicated three times for those who shaved their heads (during Hajj and Umrah). Each time, it was requested of him: And those who trim their hair (pray for them as well), so on the third time he said: "And for those who trim their hair as well."
