If one interrupts sa'y (walking between al-Safa and al-Marwah) when the prayer is called, does he repeat the lap from the beginning?

Question:
He says: Honorable Shaykh, may Allah grant you success, if I interrupt sa'y because of the call to the obligatory prayer, do I repeat this lap that I interrupted from the beginning, like the tawaf (circumambulation of the Ka'bah) before it, which was valid before the lap?

Answer:
As for the lap in which you prayed, you interrupted it, so you repeat it from the beginning.
