Questions on the Explanation of the Book of Nullifiers of Islam

Question:
If a person leaves off the sa'y (walking between al-Safa and al-Marwah) of Hajj and then returns to it, is he required to enter the state of ihram? And is he required to perform the tawaf (circumambulation of the Ka'bah) before performing the sa'y?

Answer:
If he has already performed the tawaf, he is not required to do anything else; the first tawaf is sufficient. He performs the sa'y, and that is sufficient. He is not required to enter ihram because he has already exited the state of ihram by performing the first exit (tahallul al-awwal) and removing the ihram garments. He comes without ihram and performs the sa'y. However, if he has not performed the tawaf, he must perform the tawaf before the sa'y.
