Shaykh Ibn al Qayyim, rahimahullaah:
Yahya bin Mu'adh said: "The intelligent one seeking the dunya is better than the ignorant one abandoning it."
The smart one calls the people to Allah from their dunya, and this makes it easier for them to respond to him. The zahid calls them to Allah by way of abandoning the dunya, and this makes it hard for them to respond, since it is very hard to pull someone away from the breast that he has developed his mind while suckling on..."
[al-Fawa'id p. 233-234]then to abandon sins and to detach oneself from them.
