Is it obligatory for someone who intended to perform Hajj, but then suffered an injury that prevented him from completing its rituals (standing at Arafah, spending the night in Muzdalifah, stoning the Jamarat, Tawaf Al-Ifadah, and Sa'i), and then exited the state of ihram by sacrificing an animal, to compensate for that Hajj with another Hajj, or is performing only Tawaf and Sa'i sufficient, knowing that he is a resident of Makkah Al-Mukarramah and has performed Tawaf and Umrah more than once?

If the ihram was made with an wavering intention, it is not valid from the outset. However, if it was made with a firm intention and then the pilgrim wavered, his ihram is valid.

If the standing at Arafat was completed, then the Hajj is complete, with the obligation of a sacrifice (dam) for every obligatory rite that was abandoned. So, whoever abandoned staying overnight in Muzdalifah, or stoning the Jamarat, or staying overnight in Mina, must offer a sacrifice.

As for the tawaf and sa'i thereafter, they suffice for what remains of the Hajj tawaf and sa'i, and the ihram for Umrah does not become valid because the pilgrim was already in the state of ihram for Hajj.

If the marriage occurred after the tawaf and sa'i in the first Umrah, it is valid.

If the marriage occurred before the tawaf and sa'i and after the time for stoning had passed, it is hoped that the contract is valid, but it is more cautious to renew it.

The intercourse is considered intercourse of شبهة (sexual intercourse in good faith due to a mistaken belief), and the children are attributed to the spouses. Repentance is obligatory for not having referred to people of knowledge.
