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."
Sahih al-Bukhari Book 25, Hadith 206
