The one performing Ifrad and the one performing Qiran are not required to perform another Sa'y

Question: I performed Hajj as an individual (Ifrad) and I performed the Tawaf and Sa'y before 'Arafah. Am I required to perform Tawaf and Sa'y upon my descent (from 'Arafah) or with the Tawaf of Ifadah?

Answer: This is the case for the one who performed Hajj as an individual, and likewise for the one who performed Hajj and 'Umrah together as a Qiran. If he entered Makkah, performed Tawaf and Sa'y, and remained in his state of Ihram because he was performing Ifrad or Qiran, and did not exit the state of Ihram, then his Sa'y is sufficient and he is not required to perform another Sa'y. So, if he performs Tawaf on the Day of 'Eid or after it, the Tawaf of Ifadah is sufficient for him, provided he did not exit his state of Ihram until the Day of Sacrifice. The Sa'y he performed first is sufficient, whether he had a sacrificial animal or not, if he did not exit his state of Ihram until after he descended from 'Arafah on the Day of 'Eid. In that case, his first Sa'y is sufficient for him and he does not need a second Sa'y, whether he was performing Qiran with Hajj and 'Umrah or performing Ifrad for Hajj.
The second Sa'y is only required for the one performing Tamattu', who entered the state of Ihram for 'Umrah, performed Tawaf and Sa'y for it, and exited the state of Ihram, and then entered the state of Ihram for Hajj. For this person, a second Sa'y for Hajj is required, distinct from the Sa'y of 'Umrah.
