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 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.
Ali ibn Abi TalibAsceticism is not that you should not own anything, but that nothing should own you.
