Marital relations during ইহরাম is the most severe violation of the ইহরাম state. Scholars unanimously agree that if a হাজী has sexual intercourse before the first tahalul (which occurs on the Day of Sacrifice after stoning Jamrat al-Aqabah, shaving/cutting hair, and either তাওয়াফ or sacrifice), the consequences are extremely serious. There are three mandatory consequences according to the consensus of the four schools:
First, the হজ্জ is invalidated (fasid). However, the হাজী must complete all remaining rites of the হজ্জ as if it were valid — they cannot simply stop and go home. Second, the হাজী must perform the হজ্জ again the following year to make up for the invalidated one, as the obligation of হজ্জ remains unfulfilled. Third, the হাজী must pay a kaffarah, which জমহুর উলামাদের মতে is sacrificing a camel. If unable to find or afford a camel, they sacrifice a cow. If unable, they sacrifice seven sheep.
Sheikh Ibn Baz explained that both spouses bear the sin if both were willing participants, and both must make up the হজ্জ. The kaffarah is shared between them according to one opinion, while another opinion requires a kaffarah from each. Sheikh Ibn Uthaymeen clarified that if the intercourse occurs after the first tahalul but before তাওয়াফ al-Ifadah, the হজ্জ is not invalidated according to the majority, but the হাজী enters a state of partial ইহরাম, must exit the Haram to re-enter ইহরাম from the nearest boundary, perform তাওয়াফ al-Ifadah, and sacrifice a sheep. This is a lesser penalty than the pre-tahalul violation. Al-Fawzan noted that ignorance of the ruling does not excuse the violation in this case according to most scholars, given the severity of the prohibition.
