"Is it permissible for a person to perform Tawaf on behalf of his relatives?" Imam (as) replied: "If he has completed the rites of Hajj, then he may do as he wishes."

I asked Abu al-Hasan (as): "I performed four circuits of circumambulation and became tired. Should I pray the associated two units of prayer while sitting?" Imam (as) replied: "No." I asked: "And how should a person pray the night prayer if he becomes tired or feels weakness while sitting?" Imam (as) said: "A person circumambulates while sitting." I said: "No." Imam (as) replied: "Then perform the prayer while standing."

“I once asked abu al-Hassan (a.s.), about my performing Tawaf in which after the fourth round of walking around the House I became tired: if I could perform its two Rak‘at Salat (prayer) in a sitting position. He (the Imam) said, ‘No, you cannot do so.’ I then asked, ‘What should a person do in such case while in Salat (prayer) of night. In this case if one feels weakness, it is permissible to perform them in sitting position, and in this case it is not permissible.’ He (the Imam) said, ‘Is it right to perform Tawaf and you are sitting?’ I replied, ‘No, it is not right.’ He (the Imam) then said, ‘Perform Salat (prayer) while you are standing.’”

I asked Abu al-Hasan (as) about a man who performed the sa‘i between Safa and Marwa, completing three or four circuits, then urinated and completed the rest of his sa‘i without wudu. Imam (as) said: "There is no harm in it, but if he had completed his rituals with wudu, it would have been more preferable to me."
