Allah, Mighty and Exalted, says, My servant endears himself to Me with nothing more beloved to Me than what I have made obligatory upon him, and he endears himself to Me through performance of the supererogatory prayers until I love him. Once I love him, I become his hearing with which he hears, his sight with which he sees, his tongue with which he speaks, his hands with which he acts, and his foot with which he walks. When he calls Me I answer him, and when he asks Me I grant him.'
