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

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.

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.

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.

O you, who spends his lifetime disobeying his Lord, no one amongst your enemies is wicked to you more than you are to yourself

O you who sold yourself for the sake of something that will cause you suffering and pain, and which will also lose its beauty, you sold the most precious item for the cheapest price, as if you neither knew the value of the goods nor the meanness of the prize. Wait until you come on the Day of Mutual Loss and Gain and you will discover the injustice of this contract.

This wordly life is like a shadow. If you try to catch it, you will never be able to do so. If you turn your back towards it, it has no choice but to follow you.
