Do not use the sharpness of your speech on your mother who taught you how to speak.
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 TalibEither you are just or unjust. If you are just, then you will not keep aloof from the people, but will listen to them and meet their requirements. But if you are unjust, the people themselves will keep away from you.
