Imam explains through his theological works as following:
Think a little, look ahead, weigh the consequences of yours deeds, keep in mind the perilous events which take place after death, the pressure of the grave, the world of barzakh (the period between death and resurrection), and do not neglect the difficulties which will follow that.
Hell is lit with the ugly works and deeds of man.
If a man does not light the fire by his works and deeds, hell will be extinguished. The interior of this disposition is hell. To approach this disposition is to approach hell.
That which occurs to this ‘alim in the next world is something which has been prepared in this world.
Before loosing the opportunity, you should try to remedy this.
You young people are advancing toward old age, and we old people toward death.
With every breath and every step you take, and with each passing moment of your life, reform becomes more difficult, and it is possible for darkness and corruption to increase.
While you enjoy the strength and determination of youth you can expel selfish desires, worldly attractions and animal wants from yourselves.
A young heart is subtle and celestial, and within it the motivation for corruption is weak. However, the older one gets the stronger and more firm is the source of sin implanted in the heart, until it can no longer be uprooted.
Repentance is not merely the verbal expression, “I repent before Allah,” rather, contrition and the resolve to abandon one’s sin are also necessary.
Behave well with people, and in company, and be compassionate and kind.
Behave well with the good and righteous servants of God.
Someone from whose hands, tongue and eyes other Muslims are not safe is not truly a Muslim.
To slander one of the servants of God is to slander God.
Someone who pursues selfish desires and who is obedient to Satan gradually turns the color of Satan.
