I looked at all the friends and did not find a better friend than safeguarding the tongue. I thought about all the dresses but did not find a better dress than piety. I thought about all sorts of wealth but did not find a better wealth than contentment in a little. I thought of all sorts of good deeds but did not find a better deed than offering good advice. I looked at all types of sustenance but did not find a better sustenance than patience.
Umar ibn Al Khattab
