Abd al-Rahman bin Abd al-Qari (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) prayed the morning prayer in Makkah, then made seven circuits of the House of Allah. Then he set off, intending to go to Madinah; when he reached the place called Dhu Tuwa, the sun had risen, and he prayed two rak'ahs.
