A man who omits Safa and Marwah: what he owes

Al-Hasan said, concerning a person who leaves out the sa'y between Safa and Marwah, that a sacrifice (dam) is due from him.

Dawud bin Abi Asim arrived (for Hajj or Umrah) and left out the sa'y between Safa and Marwah. Ata said: "Offer a sacrifice (shed blood)."

And Tawus said: "Enter as one performing Umrah."

Mujahid and Ibrahim said: If a pilgrim on Hajj forgets the sa'y between Safa and Marwah, then (another) Hajj is due from him; and if he is performing Umrah, then he must perform Umrah (again). Nothing will suffice for him except the sa'y between Safa and Marwah.

The same is also reported from Ibrahim through Abu Ma'shar (Mujahid and Ibrahim both said it).
