Based on Chapter 34, how did the parents of the afflicted child present their case to Sai Baba, and what was his response?

Chapter 34 details a very emotional plea from the parents. Upon arriving in Shirdi, they immediately took Baba's darshan and prostrated at his feet. With choked voices, folded hands, and pitiful faces, they narrated their child's suffering. They expressed their exhaustion and desperation, stating they could no longer bear to see their son's pain and saw no other way out. They begged Sai Samarth to place his hand of protection on their son's head. In response, Sai, described as the embodiment of compassion, reassured them completely. He told them to be worry-free and instructed them to take his Udi and smear it on the wound, promising that those who seek shelter in the Masjid shall never face downfall.
