How did Sai Baba respond to the pleas of the distressed parents from Malegaon?

In Chapter 34, when the parents from Malegaon arrived in Shirdi, they prostrated at Sai Baba's feet and, with choked voices and pitiful faces, narrated their son's suffering. They pleaded for his help, expressing their exhaustion and desperation. Sai, described as the embodiment of compassion, responded by reassuring them completely. He told them to be worry-free and gave them a simple instruction: "Take this Udi and smear it on that wound." The chapter notes his powerful assurance that those who seek shelter in the Masjid shall never face downfall, providing immense comfort to the desperate parents.
