Urwah bin Zubair (may Allah have mercy on him) asked Ibn Umar (may Allah be pleased with them both) whether the Prophet (peace and blessings be upon him) performed Umrah in the month of Rajab. He replied, "Yes!" Urwah conveyed this to Aisha (may Allah be pleased with her), and she said, "May Allah have mercy on Abu Abdur Rahman. The Prophet (peace and blessings be upon him) performed every Umrah that he performed, and they (Ibn Umar and others) were with him (but he forgot that) the Prophet (peace and blessings be upon him) never performed Umrah in Rajab." Ibn Umar (may Allah be pleased with them both) neither affirmed nor denied this, but remained silent.
