Mukhtasar Bukhari

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "O Allah! Forgive those who shave their heads." The companions said: "And those who trim their hair as well." The Prophet, peace and blessings be upon him, repeated: "O Allah! Forgive those who shave their heads." The companions said: "And those who trim their hair as well." Then the Prophet, peace and blessings be upon him, said for the third time: "And forgive those who trim their hair as well."
