Is it obligatory to perform sa'y (walking between al-Safa and al-Marwah) after the tawaf (circumambulation of the Ka'bah) of Ifadah on the Day of Sacrifice?

The questioner : Very well, Shaykh, may Allah reward you with good. Regarding the other question, since you answered it: For whom is the tawaf of Ifadah obligatory, and is there a sa'y after the tawaf on the Day of Sacrifice?

The Shaykh : We mentioned that the one performing tamattu' (combining 'Umrah and Hajj with a break between them) must perform sa'y. As for the one performing qiran (combining 'Umrah and Hajj in one ihram) and the one performing ifrad (performing Hajj alone), if they performed sa'y after the tawaf of arrival, they do not repeat the sa'y a second time; otherwise, they perform sa'y after the tawaf of Ifadah.
