And verily for everything that a slave loses there is a substitute, but the one who loses Allah will never find anything to replace Him.

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.

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

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?

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.

From the perfection of Allah's ihsan is that He allows His slave to taste the bitterness of the break before the sweetness of the mend. So He does not break his believing slave, except to mend him. And He does not withhold from him, except to give him. And He does not test him (with hardship), except to cure him.

There is no captive in a worse state than the one who is captivated by his worst enemy (Shaytan) and there is no prison which is tighter than the prison of hawa (desire) and there is no bond/fetter more strong than the bond of desire. How, then, will a heart which is captivated, imprisoned and fettered travel unto Allah and the Home of the Hereafter?
