As-Salaam alaikum,
Abu Hurayra, may Allah be pleased with him, narrated that the Prophet, Sallallahu alaihi Wasallam told me:-
"O Abu Hurayra, be scrupulous and you will be the most
devoted of people; be content and you will be the most
grateful of people; love for people what you love for yourself
and you will be a believer; be a good companion to those in
your company and you will be a Muslim; and decrease laughter,
for truly, a lot of laughter kills the heart." [Ibn Majah].
