Sayyiduna Usama bin Sharik (may Allah be pleased with him) narrates: "We were present with the Prophet Muhammad (peace and blessings be upon him). It seemed as if there were birds sitting on our heads. None of us was speaking. During this time, some Bedouins came to your service. They said: O Messenger of Allah! Please give us a verdict regarding this issue. Please give us a verdict regarding this issue. The Prophet Muhammad (peace and blessings be upon him) said: O people! Allah Almighty has removed hardship from you. Except for the person who tries to dishonor his brother. This is the person who will commit sin and will be destroyed. The people asked: O Messenger of Allah! Can we use medicine? The Prophet Muhammad (peace and blessings be upon him) said: Yes! Allah Almighty has sent down a cure for every disease that He has sent down. There is only one disease that is different. The people asked: O Messenger of Allah! Which one is that? He said: Old age. The people asked: Who is the most beloved person to Allah Almighty? O Messenger of Allah! The Prophet Muhammad (peace and blessings be upon him) said: The most beloved among the people to Allah Almighty is the one who has the best character."
