The Effect of Excessive Indulgence in Permissible Matters on Khushu'

Question:
Does indulging excessively in permissible matters affect a person's heart, such as his khushu' (humility) in prayer and his fear of Allah (Glorified and Exalted is He)?

Answer:
If you give yourself what you desire and indulge it in luxury and pleasures, this makes you lazy, it makes you lazy about obeying Allah (Mighty and Majestic). If you are full, you cannot get up, and you cannot wake up for the night prayer. The Prophet (peace and blessings be upon him) said: "It is sufficient for a son of Adam to eat a few mouthfuls to keep his back straight. If he must eat more, then one-third for his food, one-third for his drink, and one-third for his breath." So a person should be moderate, because this helps him more in obeying Allah (Mighty and Majestic) and drives laziness away from him.
Also, if one immerses himself in desires, his soul may perhaps call him to forbidden things. So he should place a barrier of permissible things between himself and the forbidden things, fearing that he might fall into the forbidden things. Yes.
