Q: I went to perform Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between) this year. After I performed `Umrah before Hajj, I went to Mina on the 3rd of Dhul-Hijjah, 1400 A.H. After I put off Ihram (ritual state for Hajj and `Umrah) for `Umrah, I felt some pain and swelling in my knees which crippled me. When I consulted a doctor, he advised me to discontinue Hajj. It should be noted that I truly could not walk even one meter further because of the extreme pain resulting from this. Afterwards, I returned to Al-Madinah, where I live, on the 5th of Dhul-Hijjah, 1400 A.H. without performing Hajj. It should be mentioned here that when I intended (Part No. 11; Page No. 356) to perform `Umrah, I did not say: "If a force majeure detains me, I shall assume Ihram wherever I am detained", as the Prophet (peace be upon him) said. Is saying this statement a condition for ending Ihram? I would like your Eminence to tell me if I have to offer a sacrifice or not. If yes, is it permissible for me to nominate someone to offer this sacrifice in Makkah?
