Sayyiduna Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said:“O Abu Hurairah! Be content with what Allah has decreed for you, and you will become the richest of all people. And become pious, and you will be a devoted servant of Allah. And love for others what you love for yourself, and you will become a believer. And behave well with your neighbor, and you will become a Muslim. Avoid excessive laughter, for too much laughter kills the heart, and loud laughter is from Satan, while smiling is from Allah.”
