6 حَدَّثَنِي جَمَاعَةُ مَشَايِخِي عَنْ مُحَمَّدِ بْنِ يَحْيَى الْعَطَّارِ عَنِ الْحُسَيْنِ بْنِ أَبِي سَارَةَ الْمَدَائِنِيِّ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْحَجَّاجِ أَوْ غَيْرِهِ اسْمُهُ 3 الْحُسَيْنُ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ (ع) مَنْ زَارَ قَبْرَ الْحُسَيْنِ (ع) لَيْلَةً مِنْ ثَلَاثِ لَيَالٍ غَفَرَ اللَّهُ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ وَ مَا تَأَخَّرَ قَالَ قُلْتُ أَيَّ اللَّيَالِي جُعِلْتُ فِدَاكَ قَالَ لَيْلَةَ الْفِطْرِ وَ لَيْلَةَ الْأَضْحَى وَ لَيْلَةَ النِّصْفِ مِنْ شَعْبَانَ
6. All of my scholars narrated to me from Muḥammad ibn Yaḥyā Al-‘Aťťār, from Ḥusain ibn Abī Sārah Al-Madā`ini, from Ya’qūb ibn Yazīd, from Ibn Abī ‘Umayr, from ‘Abdil Raḥmān ibn Ḥajjāj, or from someone else named Ḥusain, who said: Abū ‘Abdillāh (Imam Sādiq (a.s.)) said: Allāh will forgive all of the past and future sins of those who go to the Ziyārah of the grave of Ḥusain (a.s.) on one of three nights. I asked, “May I sacrifice myself for you! What are the three nights?” Imam (a.s.) replied, “The night of Fiťr, the night of Aďḥā, and the night of the fifteenth of Sha’bān.”
