Musannaf Ibn Abi Shaybah 15181 — A man who makes tawaf of the House

Mujahid and Tawus said, concerning a person who forgets to pray the two rak'ahs after the obligatory tawaf: If he prays any prayer after it, that will suffice for him; and if he prays them in the nearest or the farthest part of the Haram, that will suffice; and if he leaves the Haram without praying them, he will have to offer a sacrifice.
