Reward of repenting
Thawāb al-Aʿmāl wa ʿiqāb al-Aʿmāl|Volume 1|Book 2|Chapter 354
أَبِی ره قَالَ حَدَّثَنِی سَعْدُ بْنُ عَبْدِ اللَّهِ عَنِ الْهَیْثَمِ بْنِ أَبِی مَسْرُوقٍ النَّهْدِیِّ عَنْ إِسْمَاعِیلَ بْنِ سَهْلٍ قَالَ: کَتَبْتُ إِلَی أَبِی جَعْفَرٍ ع عَلِّمْنِی شَیْئاً إِذَا أَنَا قُلْتُهُ کُنْتُ مَعَکُمْ فِی الدُّنْیَا وَ الْآخِرَهِ قَالَ فَکَتَبَ بِخَطٍّ أَعْرِفُهُ أَکْثِرْ مِنْ تِلَاوَهِ إِنَّا أَنْزَلْنَاهُ وَ رَطِّبْ شَفَتَیْکَ بِالاسْتِغْفَارِ.
4. My father رحمه الله said: it was narrated to me by Sa’d b. Abdillah from al-Haytham b. Abi Masruq al-Hindi from Ismail b. Sahl who said: The narrator wrote to Imam Muhammad Baqir عليه السلام to let him know those deeds, which will keep him along with Imam عليه السلام in this world and the hereafter. Imam عليه السلام replied, “Recite Innaa anzalnaa (Surah Qadr) extensively and your tongue should not stop from repenting.”
