2 وَ حَدَّثَنِي مُحَمَّدُ بْنُ جَعْفَرٍ عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنِ الْحَسَنِ بْنِ عَلِيِّ بْنِ أَبِي عُثْمَانَ عَنْ إِسْمَاعِيلَ بْنِ عَبَّادٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبِي سَعِيدٍ الْمَدَائِنِيِّ قَالَ دَخَلْتُ عَلَى أَبِي عَبْدِ اللَّهِ (ع) فَقُلْتُ جُعِلْتُ فِدَاكَ آتِي قَبْرَ الْحُسَيْنِ قَالَ نَعَمْ يَا أَبَا سَعِيدٍ ائْتِ قَبْرَ ابْنِ رَسُولِ اللَّهِ (ص) أَطْيَبِ الطَّيِّبِينَ- وَ أَطْهَرِ الطَّاهِرِينَ وَ أَبَرِّ الْأَبْرَارِ فَإِذَا زُرْتَهُ كُتِبَ لَكَ اثْنَتَانِ وَ عِشْرُونَ عُمْرَةً

2. Muḥammad ibn Ja’far narrated to me from Muḥammad ibn Ḥusain, from Ḥasan ibn ‘Ali ibn Abī ‘Uthmān, from Ismā’īl ibn ‘Abbād, from Ḥasan ibn ‘Ali, from Abī Sa’īd Al-Madā`ini, who said: I went to Abī ‘Abdillāh (Imam Sādiq ) and asked, “May I sacrifice myself for you! Should I go to (the Ziyārah of) the grave of Ḥusain ?” Imam replied: O Abā Sa’īd! Yes! Go to (the Ziyārah of) the grave of the son of the Messenger of Allāh ﷺ, the most blessed of the blessed ones, the most purified of the purified ones, and the most pious of the pious ones; for if you go to his Ziyārah, twenty-two ‘Umrah will be registered for you.
