7 حَدَّثَنِي مُحَمَّدُ بْنُ يَعْقُوبَ عَنْ عَلِيِّ بْنِ مُحَمَّدِ بْنِ عَلِيٍّ رَفَعَهُ قَالَ قَالَ الْخَتْمُ عَلَى طِينِ قَبْرِ الْحُسَيْنِ (ع) أَنْ يُقْرَأَ عَلَيْهِ إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ
7. Muḥammad ibn Ya’qūb narrated to me from ‘Ali ibn Muḥammad, who narrated that: He said: In order to seal the clay of the grave of Ḥusain one should recite (the chapter of) Innā Anzalnāh on it.
