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,”* “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.”

وَعَنْ أَسْمَاءَ بِنْتِ يَزِيدَ قَالَتْ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم يقْرَأ: (يَا عبَادي الَّذِي أَسْرَفُوا عَلَى أَنْفُسِهِمْ لَا تَقْنَطُوا مِنْ رَحْمَةِ اللَّهِ إِنَّ اللَّهَ يَغْفِرُ الذُّنُوبَ جَمِيعًا) وَلَا يُبَالِي رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَقَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ وَفِي شَرْحِ السُّنَّةِ يَقُولُ: بَدَلَ: يقْرَأ
