Repel the thought, for if you don't, it becomes an idea. So repel the idea, for if you don't it will become a desire. So fight against that(desire), for if you don't, it will become a determination and a passion. And if you don't repel that, it will become an action. And if you don't replace it with its opposite, it will become a constant habit. So at that point, it will be difficult for you to change it.

O people who take pleasure in a life that will vanish, falling in love with a fading shadow is sheer stupidity

Speech remains as a slave to you, but the moment it leaves your mouth, you become its slave.

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.

Whoever mocks his brother for a sin they repented from will not die till he himself falls into the same sin.

How strange! You lose a little from you and you cry. And your whole life is wasting and you're laughing

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.
