Treat Usama b. Zaid well

This hadith speaks about the importance of respecting and obeying those who are pious and dear to Allah's Messenger. It emphasizes that we should treat Usama b. Zaid with kindness, as he was most competent for it and was dearest to Allah's Messenger amongst people. We should always remember that obedience to those who are pious is a sign of our faith in God, and it will bring us closer to Him if we do so with sincerity. Furthermore, this hadith teaches us that respect for others should be based on their piety rather than their social status or wealth; thus reminding us not to judge people by their outward appearances but rather by their inner qualities such as piety or righteousness.
