Sahih al-Bukhari 1728
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "O Allah! Forgive those who get their heads shaved." The people asked. "Also 
those who get their hair cut short?" The Prophet (ﷺ) said, "O Allah! Forgive those who have their heads 
shaved." The people said, "Also those who get their hair cut short?" The Prophet (invoke Allah for 
those who have their heads shaved and) at the third time said, "also (forgive) those who get their hair 
cut short."
