'Abdullah bin 'Amr bin Al-'as (May Allah be pleased with them) reported: Messenger of Allah ﷺ did not indulge in loose talk nor did he like to listen to it. He used to say, "The best of you is the best among you in conduct". Al-Bukhari and Muslim.
The Prophet's words remind us that our behavior reflects on who we are as individuals, so it is important for us to always strive for excellence when interacting with others. We should also remember that our words carry weight, so we should think carefully before speaking or engaging in idle conversations. By following these teachings from the Prophet Muhammad, we can become better Muslims and better people overall.
