If you find that somebody is not grateful for all that you have done for him, then do not get disappointed because often you will find that someone else feels under your obligation though you have done nothing for him and thus your good deeds will be compensated, and Allah will reward you for your goodness.
Ali ibn Abi TalibA man's behavior is the index of the man, and his discourse is the index of his understanding.
Ali ibn Abi TalibDo not hate what you do not know, for the greater part of knowledge consists of what you do not know.
Ali ibn Abi TalibHow strange and foolish is man. He looses his health in gaining wealth. Then to regain health he wastes his wealth. He ruins is present while worrying about his future - but weeps in the future by recalling his past. He lives as though death shall never come to him - but dies in a way as if he were never born.
