Is the following a quote from authentic hadith by Prophet Mohamed:
Four things support the world: the learning of the wise, the justice of the great, the prayers of the good, and the valor of the brave.
I was unable to find any Hadith similar to that. But I did stumble across links that attributed the quote to Elijah Muhammed and not Prophet Muhammed (SAW).
