A friend cannot be considered a friend until he is tested in three occasions: in timeof need, behind your back, and after your death.
Ali ibn Abi TalibDo not use the sharpness of your speech on your mother who taught you how to speak.
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.
Ali ibn Abi Talib
