Whoever desires to purify his heart, then let him prefer Allah to his desires

A true believer does not fear physical death, rather he fears the death of his heart

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.

Beware of every hour and how it passes, and only spend it in the best possible way, do not neglect yourself, but render it accustomed to the noblest and best of actions, and send to your grave that which will please you when you arrive to it.

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?

The sea of pleasures may drown its owner and the swimmer fears to open his eyes under the water.

As long as one is following the right way, one should never be concerned about the reproaches of those who like to find faults.
