He deliberately wore Makhit while knowing that he was a Muhrim

Q: My father assumed Ihram (ritual state for Hajj and Umrah) for Ifrad Hajj (performing Hajj only) during the Hajj of last year from the Miqat (site for entering the ritual state for Hajj and Umrah), put on Ihram clothing and made Talbiyah (devotional expressions chanted at certain times during Hajj and Umrah). When he reached al-Hada he deliberately wore Makhit (clothes sewn to fit body limbs) while knowing that he was a Muhrim (pilgrim in a ritual state for Hajj and Umrah). He remained in these clothes for a whole day after which he removed them along with a head covering. He stood at Arafat and performed all the rites. Is it necessary for my father to do anything or is his Hajj complete? If his Hajj is complete but he must slaughter, then where must he do this and how? Does it fulfill the obligation if he slaughters in his home country? Please answer me in detail so I could convince my father about what he must do since he has heard many different opinions.

A: Your father must make a Fidyah (ransom) because he wore Makhit intentionally, knowing that he was in a state of Ihram. Even if he wore the Makhit due to an illness, such as cold, he must still make a Fidyah which consists of slaughtering a sheep which fulfills the requirements of the Ud-hiyah (sacrificial animal offered by non-pilgrims) and distribute its meat among the poor of Makkah, feeding six Miskins (needy) each with half a Sa` (1 Sa`=3 kg. Approx.) of dates, wheat or any other type of the staple food of the country. This is to be given to the poor and Miskins of Makkah. Alternatively, he may observe Sawm (Fast) for three days in Makkah or any other place. He is to make another similar Fidyah (ransom) for deliberately covering his head while assuming Ihram (ritual state for hajj and Umrah). Your father must make sincere Tawbah (repentance to Allah) for having deliberately worn Makhit and for covering his head while assuming Ihram because he did something which the Prophet (peace be upon him) prohibited.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
