What should I do if the prayer (Salat) is called while I am performing Tawaf or Sa'i: Should I complete the Tawaf/Sa'i, or should I pray and then restart the Tawaf/Sa'i?

If the prayer is established during the circumambulation (Tawaf) or the ritual walk (Sa'i), one should interrupt the Tawaf or Sa'i and pray with the Imam. Then, one should complete the Tawaf or Sa'i from the point where it was interrupted, and there is no need to restart it from the beginning.
