The respected Maulavi narrated that:

My brother, Muhammad Ishaq, contracted the disease of consumption. My father took him to Karbala Moalla and tied him to the sepulcher of His Eminence, Abu! Fadhl Abbas; beseeched him to pray for his recovery or death. After that he became engrossed in praying in the verandah. When he came back to the child, he said: Father, I am hungry. He glanced at his face and saw that the color of his cheeks had changed and he had recovered. He brought him out. In the morning, he asked for a pomegranate and ate eight fruits and a big loaf of bread. Even then the disease did not affect him. Now, he lives in Najaf al-Ashraf and works as a bread maker in Hazrat Hamza.

In one of my journeys, I performed the Ziyarat of Hazrat Hamza and in company of the Maulavi, I met this Muhammad Ishaq. I found that signs of piety and abstinence were apparent in him.
