Concept:There are three recognised forms of Hajj, and they differ by whether and how Umrah is joined with the Hajj rites.
Explanation:In Qiran, the pilgrim enters ihram with the intention of performing both Hajj and Umrah together as a single combined act.
In Ifrad, the pilgrim performs only Hajj without Umrah.
In Tamattu', the pilgrim performs Umrah first, then later assumes ihram again for Hajj within the same journey.
Ithnayn is an Arabic term that simply means "two"; it is not a recognised type of Hajj in Islamic law.
Only Qiran matches the meaning of "Hajj combined with Umrah."
Answer:Hajj combined with Umrah is known as Qiran. The correct option is C. qiran.
