Is it necessary to repeat the Hajj for someone who forgot the intention for the circumambulation (tawaf) and the ritual running (sa'i) of Hajj?

If you performed Tawaf and Sa'i without the explicit intention that they were the Tawaf al-Ifadah and Sa'i of Hajj, scholars have differed regarding their sufficiency. The Shafi'is leaned towards them being sufficient, arguing that the intention for Hajj encompasses all its rituals, and that intention is a simple matter that follows knowledge; whoever knows what he intends to do has already intended it. Consequently, your Hajj is valid, and you are not required to repeat the Tawaf or Sa'i.
