No one can indulge in unlawfulness except for two reasons, the first of which is failing to trust in Allah, despite the fact that if one obeys Him, he will surely be granted the best of lawful gains.

The second reason is knowing that whoever abandons anything for the sake of Allah, surely He will grant him something better than what he has abandon.

Unfortunately, his vain desires surpass his patience and his inclination overpowers his mind, The first one has poor knowledge, and the second one has poor insight.

-Imam Ibn Qayyim
