What should be considered to attain khushu (devotional humility) in prayer?

In the Qur’an, performing prayer with khushu is mentioned as one of the distinguishing qualities of the believer (al-Mu’minun, 23/2). The Messenger of Allah (peace be upon him) indicated the special status of prayer by saying, “Prayer has been made the delight of my eyes.” (Nasa’i, ‘Ishrat al-nisa, 1 [3939-3940]). Khushu in prayer is achieved by distancing oneself from distracting external factors and allowing the heart to connect with Allah (the Exalted). A person’s inner experiences and thoughts affect their khushu in prayer and are reflected in their actions. Therefore, while performing prayer, one should be conscious of standing in the presence of Allah, turn to prayer with both mind and heart, and avoid actions such as looking around, playing with one’s clothes, or neglecting the proper fulfillment of the prayer’s pillars (ta’dil al-arkan). One should strive to focus on the meanings of the surahs and remembrances being recited. Additionally, one should try not to follow distracting thoughts that come to mind during prayer and make an effort to recollect oneself by remembering that they are in the presence of their Lord.
