Fear the sins that you commit in secret, because the Witness of those sins is the Judge Himself!
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.
Ali ibn Abi Talib
