Chapter 2: Surat Al-Baqarah (The Cow), verses 26-29

Translation:
God does not hesitate to give parables about gnats or even smaller creatures. Those who believe know that it is the truth from their Lord, but those who disbelieve ask: ‘What could God mean by this parable?’ By it God misleads many and enlightens many. But He misleads none except the evil-doers, who break His covenant after accepting it, and sever what He has bidden to be joined and make mischief in the land. These are the losers. How can you deny God? Did he not give you life when you were dead, and will He not cause you to die and then restore you to life? Will you not return to Him at last? He created for you all that the earth contains; then, turning to the sky, fashioned it into seven heavens. He has knowledge of all things.
Tafsir
(Commentary):
Man’s
first duty to God is to be true to the covenant made between the Creator and His
creatures at the beginning of the world, namely, that man should remain God’s
servant. Then, his conduct towards his fellow man should be such that all the
ties that God wishes may be consolidated. Thirdly, when God appoints some mortal
to preach His word, man should not turn others away from the chosen one’s
preaching by inventing groundless arguments against it. The message of truth
seeks to harmonize man with his own nature: those who prevent others from
receiving it are guilty of making ‘mischief in the land’.
God
has created man from nothing. This is a favour great enough to make man humble
himself before God. But God has not just created man and left him to his own
devices: He has given him an earth made in perfect accord with him. Yet, all
God’s beneficence notwithstanding, man is constantly living under peril of
death: and immediately after his demise, he will be brought before the Lord of
the Universe to be judged. The knowledge of this should make him devote himself
entirely to God; it should make him remember and obey God throughout his life,
even remaining God’s humble servant.
