Obey Allah’s Messenger’s orders , Strive towards purity through Islamic teachings .

This hadith speaks about the power of Medina in purifying people's hearts and souls. It tells us that when a desert Arab swore an oath of allegiance to Allah's Messenger, he later wanted to cancel it due to suffering from fever in Medina. However, the Prophet refused his request as he believed that being in Medina would help him purify himself from any impurities or wrongdoings he may have committed before coming there. Eventually, this man cancelled his own oath and left without permission from the Prophet; however, even then the Prophet still praised how powerful being in Medina was for purifying one's heart and soul. This hadith teaches us that we should strive to be better people by living our lives according to Islamic teachings so we can become purified individuals with strong faith in Allah SWT.
