Amr bin Maymun (may Allah have mercy on him) said: I was present with Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) at Jam' after the morning prayer, and he said: The polytheists would not depart until the sun had risen, and they used to say: 'Ashriq Thabir' (Shine, O Thabir!). the Messenger of Allah (peace and blessings be upon him) opposed them and departed before sunrise.
