Hadith 8:982
Abu Bakr narrated to us, he said: Usama narrated to us, from Ubaydullah, from Nafi’, from Ibn Umar, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "May Allah have mercy on those who shave." They said: "O Messenger of Allah, and those who shorten?" He said in the third [instance]: "And those who shorten."
