I asked him about a man who entered into Ihram for Hajj Ifrad (Hajj alone). When he entered Mecca, he performed Tawaf around the Kaaba, then joined his companions who were shortening their hair, and he also shortened his hair with them. Later, he remembered that he was in Ihram for Hajj Ifrad. Imam (as) said: "There is no penalty upon him. After offering his prayer, he should renew the Talbiyah (declaration of intention)."
