It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said:“O Abu Hurairah, be cautious, and you will be the most devoted of people to Allah. Be content, and you will be the most grateful of people to Allah. Love for people what you love for yourself, and you will be a (true) believer. Be a good neighbor to your neighbors, and you will be a (true) Muslim. And laugh little, for laughing a lot deadens the heart.”
