It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "O Allah, forgive those who shave their heads." The people said, "O Messenger of Allah! Pray for those who shorten their hair as well." The Noble Prophet (peace and blessings be upon him) then, on the fourth time, said for those who shorten their hair: "O Allah, forgive those who shorten their hair as well."
