One of the senior scholars of Najaf once said to Shaykh Abbas-e-Qummi, “My foot is constantly hurting me – please pray for me.”
The Shaykh replied, “If I say I will pray for you, it is possible that my prayer may not be answered if I have uttered something sinful in the past.
However, I will pass my hand over your foot, because with this hand I have written many ahadith of the Ahlu’l Bayt (AS) and Insha’Allah Imam Sadiq (AS) will effect a cure for you.”
He rubbed his hand over the scholar’s foot and the pain left him immediately.
