There is no rest for the person who has envy, and there is no love for the person who has bad manners.
Ali ibn Abi TalibIf 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 TalibIn this world, man is a target of death, an easy prey to calamities, here every morsel and every draught is liable to choke one, here one never receives a favour until he loses another instead, here every additional day in one's life is a day reduced from the total span of his existence, when death is the natural outcome of life, how can we expect immortality.
