Marifah.net - Knowledge and Realisation

Worship means to draw closer to Allah (swt) in full submission and with humility before Him, by means of those words and deeds that He established for His servants, whether they be actions of the heart, the body, or the spiritual state. Worship has a sweetness and a delight; and when a person tastes its sweetness, and samples its delectation, he becomes attached to it, and yearns for it, and so he never allows himself to be separated from it, because it becomes his source of tranquillity and repose.
