In 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.
Ali ibn Abi TalibHe 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.
