Causes of Khushu' in Prayer

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: I suffer from a lack of khushu' (humility) in my prayer. What are the causes that bring khushu' to the prayer and the pleasure derived from it?

Answer:
Before you enter into the prayer, stay away from distractions. For this reason, the Prophet (peace and blessings be upon him) forbade praying in the presence of food, because it occupies one's mind with the desire for food. He also forbade a person from praying while struggling to relieve himself of the two impurities, urine and feces; one should get rid of them so that their evil does not distract him.
Regarding his prayer, he should enter into it with a clear mind, with nothing distracting him, freeing his mind for the worship of Allah (Mighty and Majestic). He should not be in the presence of food, nor struggling to relieve himself of the two impurities, nor in a place that is extremely hot or extremely cold. He should stay away from these things. Yes.
