Asma’ daughter of Yazid said she heard God’s messenger reciting, “My servants who have transgressed against their souls, do not despair of God’s mercy, for God pardons all sins,”* [adding] “and He does not care.”
*Qur’an, xxxix, 53.
Ahmad and Tirmidhi transmitted it, the latter saying this is a hasan gharib tradition. Sharh as-sunna has “saying” instead of “reciting.”
