123. To Allah do belong the unseen (secrets) of the heavens and the earth and to Him goeth back every affair (for decision): then worship Him and put thy trust in Him: and thy Lord is not unmindful of aught that ye do.

Notes (Tafseer)

1626. Cf. ii. 210. There is nothing, secret or open, in our world or in Creation, which does not depend ultimately on Allah's Will and Plan. Every affair goes back to Him for decision. Therefore we must worship Him and trust Him. Worship implies many things: e.g., (1) trying to understand His nature and His Will: (2) realising His goodness and glory, and His working in us; as a means to this end, (3) keeping Him in constant remembrance and celebrating His praise, to whom all praise is due; and (4) completely identifying our will with His, which means obedience to His Law, and service, to Him and His creatures in all sincerity.
