On placing this request before Imaam Ahmed (rahimahullah), I heard him reply in a voice of anger, “We are more in need of you making du‘aa for us!” Hearing this, I turned to leave. As I departed, an old woman emerged from the home and asked, “Are you the person who spoke to Abu ‘Abdillah (Imaam Ahmed) (rahimahullah)?” When I replied in the affirmative, she said, “I have just left him in the state that he was making du‘aa to Allah Ta‘ala for your mother.”
I immediately returned home, and when I knocked on the door, my mother emerged, walking on her feet, until she opened the door for me. She then said to me, “Allah Ta‘ala has cured me.”
