Abu az-Zahiriyyah narrated:
"I went toTarsus, so I entered upon Abu Mu'awiyah al-Aswad after he had become blind. In his house,I saw a Mushaf (copy of the Qur'an) hanging from the wall, so I said to him: "May Allah have Mercy upon you! A Mushaf while youcannot even see?"He replied: "My brother, will you keep a secret for me until the day I die?"I said: "Yes." Then, he said to me: "Verily, when I want to read from the Qur'an, my eyesight comes back to me."
