Каф 50:40

The creation of the heavens and the earth in six days, in other words in six stages, indicates that God’s method of doing things is a gradual one. When God, in spite of being the possessor of all Powers, brings things into existence gradually on a long-term basis, man should also desist from making undue haste, but rather try to reach his goals through action marked by patience. Preaching, from beginning to end, is an act of patience. In this process one has to put up with the bitterness evinced by others, and persevere in one’s task in spite of there being no favourable results in sight. This patience-trying process can be pursued only by one whose days and nights are spent in remembrance of God, who reposes all hope not in human beings but in God and who does not fall a prey to a feeling of frustration, in spite of having lost everything. In the Bible it is mentioned that God created heaven and earth in six days and rested on the seventh day. This part of the verse ‘...nor were We ever wearied’ contradicts and corrects the biblical statement. Rest is taken by one who becomes tired. God does not become tired and, as such, He does not need rest.
