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.

The heart becomes sick, as the body becomes sick, and its remedy is al-Tawbah (repentance) and protection [from transgression]. It becomes rusty as a mirror becomes rusty, and its clarity is obtained by remembrance. It becomes naked as the body becomes naked, and its beautification is al-Taqwa. It becomes hungry and thirsty as the body becomes hungry, and its food and drink are knowledge, love, dependence, repentance and servitude.

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.

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

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

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!

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