Bulugh al-Maram 765
Ibn ’Umar (RAA) narrated that the Messenger of Allah (ﷺ) said:
“May Allah bless those who shaved." The Companions asked him, ‘O Allah’s Messenger, what about those who cut their hair short?’ They repeated their question twice (and each time he repeated his saying, ‘May Allah bless those who shaved.’) On the third time, the Messenger of Allah (ﷺ) then said, “And (may Allah bless) those who cut their hair short." Agreed upon.
