Abstract:
Regarding the issue of the quality of converting Umrah Mufradah to Umrah Tamattu' during the days of Hajj, there is a difference of opinion among scholars as to whether this transformation is compulsory (qahri) or optional (ikhtiari). The famous view among jurists is that the transformation is optional. In contrast, the famous theory of compulsory transformation is divided into two categories: some believe in compulsory transformation absolutely, and the late Sayyid Yazdi belongs to this group; others believe in compulsory transformation conditionally and with restrictions.
Machine summary:
Evidence of those who hold the view of absolute compulsory conversion The late Sayyid Yazdi, in Urwah (200), cites two pieces of evidence for his statement: First evidence: Adherence to the apparent meaning of narrations: Some narrations have an appearance of compulsory conversion, such as: A) (The sahih narration of Yaqub bin Shuayb from Imam al-Sadiq) (as) regarding someone who has performed Umrah Mufradah during the months of Hajj.
If someone also enters Mecca during the Hajj months for Umrah Mufradah, according to the theory of compulsory transformation, we must naturally commit that this individual also does not have the right to depart until they perform the acts of Hajj al-Tamattu.
The two conditions mentioned by the late Ayatollah Fazel also do not solve a problem; because it is possible that someone performs Umrah Mufradah during the Hajj months and their intention is also to remain in Mecca and perform Hajj al-Tamattu; consequently, a compulsory transformation occurs, this person becomes bound to Hajj and does not have the right to depart from Mecca.
Although even if it refers back to "Umrah," it would support compulsory transformation, yet Sayyid Yazdi's statement that relying on this narration considered the turning away of the majority as a cause for the weakness of the report, says: The apparent meaning of reports is authoritative, and we must adhere to this appearance and issue fatwas accordingly.
