He who is greedy is disgraced; he who discloses his hardship will always be humiliated; he who has no control over his tongue will often have to face discomfort.
Ali ibn Abi TalibYou should desire for others what you desire for yourself, and hate for others what you hate for yourself. Do not oppress, just as you do not like to be oppressed. Do good to others just as you would like good to be done to you. Dislike in yourself what you dislike in others. Accept that treatment from others which you would like others to accept from you. Do not say to others what you do not like to be said to you.
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.
