A person has been to Makkah to perform Hajj. On the 10th of Dhul Hijjah, he perform the lapidation of Jamarat al Aqaaba, shave his head, and another person perform the Hadi on his behalf (i.e . offered a sheep as sacrifice). He is now allowed to free from the state of Ehraam except not to involve in sexual intercourse with her spouse. He fell ill and could not perform the Tawaaf al Ifaada and Sai on same day. Late in the afternoon he went back to Mina up to the 13th Dhul Hijjah. On his return to Makkah, he perform the Sai first and complete it but fell ill again. The next morning someone take him on trolley to perform the Tawaaf al Widaa and Tawwaf al Ifaada (jointly). Is this acceptable.? Does that person has to enter Ehraam again to perform the farewell tawaaf &Tawaaf al Ifaada combinely?
