How did Sai Baba react when the distressed parents from Malegaon presented their suffering child's case to him?

As narrated in Chapter 34, when the parents of the suffering child arrived in Shirdi, they immediately took Baba's darshan and prostrated at his feet. With choked voices and pitiful faces, they pleaded with Sai Baba, describing their son's pain and their own exhaustion. In response, Sai, who is called the "embodiment of compassion," reassured them completely. He told them to be worry-free and gave them a profound assurance, stating that those who seek shelter in the Masjid shall never face downfall. He then gave them his specific, simple instruction: "Take this Udi and smear it on that wound."
