Hadith.2855 - Mu'awiyah ibn Ammar narrated: I said to Abu Abdullah (as): "A man starts performing Sa'i (ritual walking) between Safa and Marwah, and the time for prayer begins. Should he hasten to complete it, or should he pray first and then return to complete it, or should he remain in his current state until he finishes?" Imam (as) replied: "Isn't there a mosque between the two (Safa and Marwah)? No, rather he should pray first and then return to complete it." I asked: "And can he sit on Safa and Marwah?" Imam (as) replied: "Yes."

Hadith.2856 - Ali ibn al-Nu'man and Safwan narrated from Yahya al-Azraq, who said: I asked Abu al-Hasan (as) about a man performing Sa'i (ritual walking) between Safa and Marwah. If he completes three or four circuits and then meets a friend who invites him to fulfill a need or to have food, what should he do? Imam (as) replied: "If he responds to him, there is no harm in it, but fulfilling the right of Allah (swt), the Almighty, is more beloved to me than fulfilling the right of his companion."
