What was Sai Baba's response and specific instruction to the family from Malegaon in Chapter 34?

In Chapter 34, upon hearing the desperate pleas of the parents from Malegaon, Sai Baba, who is called the "embodiment of compassion," responded with immediate reassurance and a clear directive. He told the worried parents to become "worry-free." He made a profound promise, stating, "Those who seek shelter in the Masjid shall never face downfall, even at the end of an era." Following this comforting assurance, his specific instruction was simple yet powerful: he gave them his Udi and told them to go and smear it on the nephew's wound. This act, as presented in Chapter 34, was the divine remedy offered after all worldly medical efforts had failed.
