حَدَّثَنِی مُحَمَّدُ بْنُ عَلِیِّ بْنِ مَاجِیلَوَیْهِ عَنْ عَمِّهِ مُحَمَّدِ بْنِ أَبِی الْقَاسِمِ عَنْ أَحْمَدَ بْنِ أَبِی عَبْدِ اللَّهِ عَنْ أَبِیهِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ الْمُفَضَّلِ بْنِ عُمَرَ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ: صَوْمُ شَعْبَانَ وَ شَهْرِ رَمَضَانَ شَهْرَیْنِ مُتَتابِعَیْنِ تَوْبَهٌ وَ اللَّهِ مِنَ اللَّهِ

3. It was narrated to me by Muhammad b. Ali b. Majluwayh from his uncle Muhammad b. Abi al-Qasim from Ahmad b. Abi Abdillah from his father from Muhammad b. Sinan from al-Muffadhal b. Umar from Abi Abdillah who said: “One who fasts continuously from Shaban to the month of Ramadan then by Allah, these fasts would be counted among repentance of Allah, the Mighty and Sublime.”
