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?

Satan rejoiced when Adam (peace be upon him) came out of Paradise, but he did not know that when a diver sinks into the sea, he collects pearls and then rises again.

As long as you are performing prayer, you are knocking at the door of Allah, and whoever is knocking at the door of Allah, Allah will open it for him.

Had Allah lifted the veil for his slave and shown him how He handles his affairs for him, and how Allah is more keen for the benefit of the slave than his own self, his heart would have melted out of the love for Allah and would have been torn to pieces out of thankfulness to Allah. Therefore if the pains of this world tire you, do not grieve. For it may be that Allah wishes to hear your voice by way of Dua'a. So pour out your desires in prostration and forget about it and know; that verily Allah does not forget it.

If you knew the true value of yourself, you will never allow yourself to be humiliated by committing sins.

And to have spent the night sleeping and awoken regretful, is better than to have spent the night standing (in prayer) and awaken impressed with oneself!

Every gulp of air that goes out in a cause other than the cause of Allah will turn to sorrow and regret on the Day of Judgement.
