11 أَخْبَرَنِي حَكِيمُ بْنُ دَاوُدَ بْنِ حَكِيمٍ عَنْ سَلَمَةَ عَنْ أَحْمَدَ [مُحَمَّدِ] بْنِ إِسْحَاقَ الْقَزْوِينِيِّ عَنْ أَبِي بَكَّارٍ قَالَ أَخَذْتُ مِنَ التُّرْبَةِ الَّتِي عِنْدَ رَأْسِ قَبْرِ الْحُسَيْنِ بْنِ عَلِيٍّ (ع) فَإِنَّهَا طِينَةٌ حَمْرَاءُ فَدَخَلْتُ عَلَى الرِّضَا (ع) فَعَرَضْتُهَا عَلَيْهِ فَأَخَذَهَا فِي كَفِّهِ ثُمَّ شَمَّهَا ثُمَّ بَكَى حَتَّى جَرَتْ دُمُوعُهُ ثُمَّ قَالَ هَذِهِ تُرْبَةُ جَدِّي
11. Ḥukaym ibn Dāwūd ibn Ḥukaym narrated to me from Salamah, from Aḥmad/Muḥammad ibn Isḥāq Al-Qazwīni, from Abī Bakkār, who said: I took some of the dust which is close to the head of the grave of Ḥusain ibn ‘Ali (a.s.). It was a red-coloured clay. I took it to Imam Riďā (a.s.) to show it to him. He held it in his palm, smelled it, and started to cry, shedding tears. Then he (the Imam (a.s.)) said, “This is the dust of (the grave of) my grandfather.”
