The messenger of Marwan, whom he had sent to Umm Ma'qil (may Allah be pleased with her), reported that Umm Ma'qil (may Allah be pleased with her) said: I said: "O Messenger of Allah, I am a woman who has grown old and fallen ill; is there any deed that can stand in place of my Hajj for me?" He (peace and blessings be upon him) said: "Performing Umrah in Ramadan will suffice for you."
