What is the ruling on Hajj if the pilgrim performed Umrah and benefited from it, but did not enter into a new state of ihram for Hajj out of ignorance? Is a Fidyah (expiatory offering) due upon her?

The person performing Mut'ah (combining Umrah and Hajj) exits the state of Ihram after the Umrah, and then enters Ihram for Hajj with the intention of commencing the rituals. This intention is formed in the heart, and verbalizing it is not a condition, nor are ghusl (ritual bath) and cleaning oneself. Similarly, a woman enters Ihram in her regular clothes; she is not required to wear specific attire. If she performs the rituals and refrains from the prohibitions, this indicates the presence of an intention for Hajj. Sheikh Ibn Uthaymeen issued a fatwa validating the Hajj of a woman who was unaware of the types of rituals or the specific intention, because she entered Ihram as others did, citing the Prophet's (peace be upon him) hadith to Ali ibn Abi Talib. While it is obligatory to learn the rulings of worship before undertaking it, this woman's Hajj is valid.
