Ibn ‘Umar told that at the Farewell Pilgrimage God's messenger said, “O God, have mercy on those who have themselves shaved.” The people suggested that he should add those who had clipped their hair. He again said the same words, and when they made the same suggestion, he added “and those who clip their hair.” Bukhari and Muslim.
