Shaykhul-Islām Ibn Taymiyyah رحمه الله stated:
“Whoever doesn’t utilize himself in the worship of Allāh he will utilize it without his choice in the obedience of the Shaytān. Therefore, it’s a must that the soul has an occupation.”
[Jāmi’ Al-Masāil 8/228]
قال شيخ الإسلام ابن تيمية رحمه الله
من لم يستعمل نفسه في عبادة الله ، استعملها بغير اختياره في طاعة الشيطان؛ إذ النفس لابد لها من عمل
[—————— جامع المسائل ٨/ ٢٢٨]
The soul must be preoccupied with something in life. It’s important that we strive to preoccupy our souls with that which is pleasing and beloved to Allāh The Almighty. If not, then we will only become immersed in that which is from the obedience of the accursed Shaytān.
