When proven wrong, the wise man will correct himself and the ignorant will keep arguing.
Ali ibn Abi TalibThe sin which makes you sad and repentant is more liked by Allah than the good deed which turns you arrogant.
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 Talib
