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 
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 
to let him know those deeds, which will keep him along with Imam in this world and the hereafter. Imam replied, “Recite Innaa anzalnaa (Surah Qadr) extensively and your tongue should not stop from repenting.”
