5 وَ رَوَى مُحَمَّدُ بْنُ أَبِي يَسَارٍ [سَيَّارٍ] الْمَدَائِنِيُّ بِإِسْنَادِهِ قَالَ مَنْ سَقَى يَوْمَ عَاشُورَاءَ عِنْدَ قَبْرِ الْحُسَيْنِ (ع) كَانَ كَمَنْ سَقَى عَسْكَرَ الْحُسَيْنِ (ع) وَ شَهِدَ مَعَهُ

5. Muḥammad ibn Abī Sayyār Al-Madā`ini narrated through his Isnād that: Those who distribute water (to people) on the Day of ‘Āshūrā next to the grave of Ḥusain are like those who were with Ḥusain and distributed water to those in his camp.
