Abd al-Rahman bin al-Aswad said that his father went up to Sayyiduna Ibn al-Zubayr (may Allah be pleased with them both) on the Day of Arafah and asked him: What has prevented you from saying the talbiyah? I heard Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) saying the talbiyah in this place of yours. So he too said the talbiyah.
