Is it permissible to consider the Farewell Tawaf (circumambulation) as Tawaf Al-Ifadah (the circumambulation of overflowing/return) if the major disencumbrance has not yet been performed, particularly in a case where Tawaf Al-Ifadah was not performed due to ignorance?

The Tawaf Al-Ifadah (circumambulation of outpouring) is a pillar (rukn) without which the Hajj is invalid and cannot be compensated for by an animal sacrifice (dam). If someone misses it out of ignorance, they must return to perform it, and perform Sa'i (ritualistic walking between Safa and Marwah) afterward if they haven't performed Sa'i before, and they remain in the state of ihram. Some jurists are of the opinion that the Tawaf Al-Wada' (farewell circumambulation) suffices for Tawaf Al-Ifadah. Therefore, if the questioner performed Tawaf Al-Wada' and then performed Sa'i (if Sa'i was required of her), that would suffice for both Tawaf Al-Ifadah and Sa'i. This is the view of the Shafi'i school. However, if she did not perform Tawaf Al-Wada', or performed it but did not perform Sa'i, and returned to her country, she remains in her state of ihram, and she must return to Mecca to fulfill what is incumbent upon her. If she is unable to return (due to illness or lack of funds), she is in the ruling of one who is prevented (muhsar). She should then exit ihram by sacrificing a sheep and cutting some hair with the intention of exiting ihram. The Tawaf, however, remains an obligation upon her until she performs it or until Hajj is performed on her behalf.
