Chapter on the Trimming or Shaving for the Mutamatti‘, His Release From Ihram, and the Rulings for One Who Forgets to Trim Until He Engages in Intimacy or Commences the Hajj

Mu'awiyah ibn Ammar asked Abu Abdullah عليه السلام about a man performing tamattu‘ who had intercourse with his wife before trimming his hair. Imam عليه السلام said: "He must slaughter a camel. I fear that his Hajj may be invalid if he acted knowingly. However, if he acted out of ignorance, there is no penalty upon him." Mu'awiyah also said: I asked him about a person performing tamattu‘ who bites their nails with their teeth or trims their hair using a sharp-edged tool. Imam عليه السلام said: "There is no harm in it. Not everyone has access to scissors."
