“I wrote to abu Muhammad (a.s.) requesting him to pray for because of the pain that I suffered in my eyes. One of my eye had gone and the other was about to go. He wrote back to me in reply, “Allah has kept your eye for you.” My painful eye then recovered. He had signed at the end with these words, “May Allah, grant you good rewards and best recompense.” I became sad and I did not know anyone just passed away from my family. After a few days I received information of the death of my son, Tayyib. I then realized what for his condolences to me were.”
