Sahih Bukhari Volume 002, Book 026, Hadith Number 813.
Narated By 'Ikrima : The people of Medina asked Ibn Abbas about a woman who got her menses after performing Tawaf-al-Ifada. He said, "She could depart (from Mecca)." They said, "We will not act on your verdict and ignore the verdict of Zaid." Ibn Abbas said, "When you reach Medina, inquire about it." So, when they reached Medina they asked (about that). One of those whom they asked was Um Sulaim. She told them the narration of Safiya (812).
