Hadith.829 - Imam عليه السلام said:
"Prostrating on the clay from the grave of Imam Hussain ibn Ali عليه السلام illuminates to the seventh layer of the earth."
Whoever possesses a prayer bead (subha) made from the clay of the grave of Imam Hussain ibn Ali عليه السلام, is considered as having performed tasbih (glorification) even if they do not actively recite.
Additionally, performing tasbih with one's fingers is superior to using anything else because the fingers will be questioned (held accountable) on the Day of Judgment.
