When there is money in your hand and not in your heart, it will not harm you even if it is a lot; and when it is in your heart, it will harm you even if there is none in your hands.

Yearning for Allah and His meeting is like the gentle breeze blowing upon the heart, extinguishing the blaze of the Dunya. Whosoever caused his heart to settle with his Lord shall be in a state, calm and tranquility, and whosoever sent it amongst the people shall be disturbed and excessively perturbed.

There is no joy for the one who does not bear sadness, there is no sweetness for the one who does not have patience, there is no delight for the one who does not suffer, and there is no relaxation for the one who does not endure fatigue.

We should know that Allah has created us to live an eternal life with no death, a life of pride and ease with no humiliation, a life of security with no fear, a life of richness with no poverty, a life of joy with no pain, a life of perfection with no flaws. Allah is testing us in this world with a life that will end in death, a life of pride that is accompanied by humiliation and degradation, a life that is tainted by fear, where joy and ease are mixed with sorrow and pain.

The sinner does not feel any remorse over his sins, that is because his heart is already dead

Sins have many side-effects. One of them is that they steal knowledge from you.

Repel the thought, for if you don't, it becomes an idea. So repel the idea, for if you don't it will become a desire. So fight against that(desire), for if you don't, it will become a determination and a passion. And if you don't repel that, it will become an action. And if you don't replace it with its opposite, it will become a constant habit. So at that point, it will be difficult for you to change it.
