Assuming Ihram for Hajj then falling sick after leaving Muzdalifah and being hospitalized before returning home

Q: I traveled last year to perform Hajj with my wife and two daughters who are aged eight and six . We entered the state of Ihram with the intention for Hajj at the Miqat (sites for entering the ceremonial state for Hajj and `Umrah). However, we did not stipulate a condition while entering Ihram by saying: "If something prevents me (from completing Hajj), I will exit Ihram at the point where I am prevented (from continuing)." Then I entered Makkah to perform Ifrad Hajj (performing Hajj only). (Part No. 11; Page No. 352) I made Tawaf (circumambulation of the Ka`bah) and Sa`y (going between Safa and Marwah) on the seventh day of Dhul-Hijjah, then I moved to Mina and stayed the eighth day of Dhul-Hijjah there, then I headed to `Arafah on the ninth day and stayed there until after sunset. At midday on the day of `Arafah, I felt terribly ill and took some medication. My health did not improve and then after sunset on the day of `Arafah, I went to Muzdalifah and slept there until dawn. My health continued to deteriorate to the extent that I was taken by ambulance to the hospital in Mina where I stayed the whole day of `Eid. As a result, I was unable to perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj), or stone the pillars, as was the case with my children. Furthermore, I did not delegate anyone to perform the ceremonial stoning (of the pillars during Hajj) on my behalf.At the end of the day of `Eid I left the hospital, though still sick, and wore my regular clothing and left Makkah without performing Tawaf or the stoning (of the pillars during Hajj). When I arrived in Al-Ta'if I did not know what to do. I was admitted to the hospital in Al-Ta'if and then later discharged. No one informed me about what I should do. Finally, I returned to Najran. What should I do regarding Tawaf-ul-Ifadah which I did not perform in its due time?Similarly, what should I do with regard to the ceremonial stoning which I also did not perform?What should I do regarding having worn my regular clothing before performing Tawaf, missing the ceremonial stoning, as well as having had sexual intercourse with my wife before Tahalul (coming out of the ceremonial state for Hajj and `Umrah) that is, after my arrival in Najran? What should I do concerning my daughters who both made the intention to perform Hajj with us?Would Your Honor please clarify what I must now do to (Part No. 11; Page No. 353) please Allah (Glorified and Exalted be He), for I fear His wrath and punishment, and I want to obey Him.I ask Allah that he may bless and guide you to what is beneficial for all Muslims. I hope that Your Honor will send a written reply to my address, so that I can offer the sacrificial animals in obedience to Allah, may He accept from us.
