A man performed only four rounds of Tawaf-ul-Ifadah

Q: A man performed only four rounds of Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and did not ask anyone about that. During the next year, he performed Hajj on behalf of his dead father and offered all the pillars and obligatory acts perfectly. However, he did not perform Tawaf-ul-Ifadah for himself, thinking that its time had elapsed. The question is: Is his Hajj on behalf of his father valid?

A: His Hajj is valid but he has to return to Makkah and perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) of his first Hajj and do the Sa`y (going between Safa and Marwah during Hajj and `Umrah). If he is married and copulated with his wife, it is obligatory on him to offer a sheep meeting the same conditions for Ud-hiyah (sacrificial animal offered by non-pilgrims) to be slaughtered in Makkah and distributed among the poor. He should not eat from it. Moreover, it is obligatory on him to stay away from having sexual intercourse with his wife until he performs Tawaf and Sa`y.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
