“I once asked abu ‘ Abd Allah (a.s.), about a man who visits the House before shaving his head. He (the Imam) said, ’It is not proper unless it is because of forgetfulness.’ He (the Imam) then said, ’People came to the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, on the day of al-Nahr (slaughtering the offering, 10th of Dhu al-Hajjah). Certain ones among them said, ‘O Messenger of Allah, I shaved before slaughtering my offering.’ Another one said, ‘I shaved before throwing pebbles.’ They did not leave anything that they were required to do later but that they had done it first. He (the Messenger of Allah) said it is not harmful.’”
