Yahya related to me from Malik from Nafi from Abdullah ibn Umar
that the Messenger of Allah, may Allah bless him and grant him peace,
said, "O Allah, have mercy on those who shave their hair." They said,
"And those who shorten (their hair), Messenger of Allah." He said,
"O Allah, have mercy on those who shave." They said, "And those who
shorten, Messenger of Allah." He said, "And those who shorten."
Muwatta Malik Book 20, Hadith 196
