How did Sai Baba respond when the parents of the suffering child pleaded for his help in Shirdi?

Chapter 34 describes Sai Baba's compassionate response to the desperate parents. When they arrived in Shirdi, they prostrated at his feet and narrated their child's suffering with choked voices. They pleaded with Sai Samarth to place his protective hand on their son and remove the ailment, expressing that they had come seeking refuge with total devotion. Sai, described as the embodiment of compassion, immediately reassured them. He told them to be free from worry and gave them a simple instruction: "Take this Udi and smear it on that wound." He also gave them a profound assurance that those who seek shelter in his Masjid shall never face downfall.
