Hadith.2813 - It is narrated by Safwan from Yahya al-Azraq, who said
I asked Abu al-Hasan (as) about a man who performed the sa‘i between Safa and Marwa, completing three or four circuits, then urinated and completed the rest of his sa‘i without wudu.
Imam (as) said: "There is no harm in it, but if he had completed his rituals with wudu, it would have been more preferable to me."
