luqman the wise is one of them and he is the one who said there are three people you will not know except when you meet three others the forbearing one when you are angry the brave one when you are afraid and the brother when you are in need.
أن لقمان الحكيم منهم، وهو الذي يقول ثلاثة لا تعرفهم إلا عند ثلاثة الحليم عند الغضب، والشجاع عند الخوف، والأخ عند حاجتك.
