Musannaf Ibn Abi Shaybah 14136 — The virtue of shaving

It is narrated from Sayyiduna Malik bin Rabi'ah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) prayed: "O Allah, forgive those who shave their heads." The Companions said: "O Messenger of Allah (peace and blessings be upon him), and those who shorten their hair too?" He (peace and blessings be upon him) said: "And forgive those who shorten their hair as well." The narrator says: That day my head was shaved, and because of this prayer of the Prophet (peace and blessings be upon him) I felt greater joy than if I had been given red camels, or a great many camels.
