Abu Al-Hassan Musa (asws) having said: ‘Amir-ul-Momineen (asws) used to bequeath to his (asws) companions saying: ‘I (asws) bequeath you to fear Allah (azwj) for it is happiness for the truthful seeker, and a heavy shackle for the runaway fugitive. And be aware of the piety realising it within yourselves, and remember Allah (azwj) with a sincere Remembrance, being revived by it, and journey upon the path of salvation. Look at this world with the vision of the ascetics, the ones who have parted from it, for it dislodges its residents and causes distress to the affluent ones who (superficially) feel safe. Do not hope for those that are turned away from it, not knowing what it is that will come from it. So await patiently for the prosperity upon the arrival of the afflictions from it, and the survival from it up to the end. So its happiness is tainted with the grief, and the survival in it is up to the weakness and the fragility. So it is like a garden, the pasture of which is dense causing those who look at it, to wonder at it. Its drinks are sweet, its covering (soil) is good, its roots are excited in the ground, and its branches drip moisture until the grass reaches its due level. The scent gets triggered under the blades and gets separated from it in the morning, just as Allah (azwj) has Said: “[18:45] then it becomes dry broken into pieces which the winds scatter; and Allah is the holder of power over all things.” Look at this world and the numerous things which cause you to wonder, and the scarcity of the things which benefit you’.
