The Impact of Īmān on One’s Attentiveness in Prayer

Imām Ibn Taimiyyah, may Allāh have mercy on him, said:

[W]hen a slave’s īmān¹ gets strong, his heart becomes attentive during prayer[.]

¹Īmān is speech, action, and beliefs; it increases with acts of obedience to Allāh and decreases with acts of disobedience to Him (tr.).
