How is it possible for one’s heart to be certain that one is going to meet Allah, that Allah sees and hears all that he does, and knows his secret open affairs, and that he will be made to stand before Allah, answerable for all his deeds - how can one be certain and aware of all of this, and yet persist upon things which displease Allah; persist upon abandoning Allah’s orders, neglecting His rights, and yet claim that he has good expectation of Allah?

Doom comes about because of neglecting to evaluate one's self and because of just following one's whims.

The soul will never become pious and purified except through undergoing afflictions. It is the same as gold that can never be pure except after removing all the base metals in it.

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

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.

Losing time is harder than death, as losing time keeps you away from Allah and the Hereafter, while death keeps you away from the worldly life and people.

Everything that is loved, if it is not loved for His sake then this love is nothing but distress and punishment. Every action that is not performed for His sake then it is wasted and severed. Every heart that does not reach Him is wretched; veiled from achieving its success and happiness.
