Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that I had a great desire to ask Sayyiduna Umar (may Allah be pleased with him) about (those two noble wives of the Prophet ﷺ), but I did not have the courage, and two years passed. Then once Sayyiduna Umar (may Allah be pleased with him) set out for Hajj, and I was with him. On the way, Sayyiduna Umar (may Allah be pleased with him) started walking away from the people, so I also followed him carrying a water vessel. He fulfilled his natural need, and when he returned, I poured water on his hands and said: O Commander of the Faithful! Who are those two women who wanted to prevail over the Prophet ﷺ? He replied: Aisha and Hafsa (may Allah be pleased with them both).
