Hadith.2824 - Safwan narrated from Ishaq ibn Ammar: I asked Abu Abdullah عليه السلام about a man who performed Tawaf around the Ka'bah and then went out to perform Sa’y between Safa and Marwah. While he was performing Sa’y, he remembered that he had left part of his Tawaf incomplete. Abu Abdullah عليه السلام replied: "He should return to the Ka'bah, complete his Tawaf, and then return to Safa and Marwah to finish the remaining Sa’y." I further asked: "What if he began with Safa and Marwah before performing Tawaf around the Ka'bah?" Imam عليه السلام replied: "He should go to the Ka'bah, perform Tawaf, and then restart his Sa’y between Safa and Marwah." I then inquired: "What is the difference between these two cases?" Imam عليه السلام replied: "In the first case, he had already entered into part of the Tawaf, whereas in the second case, he had not yet begun any part of it."
