57:8Al-Hadid

And why should you not believe — an address to the disbelievers — in other words there is nothing to prevent you from believing in God when the Messenger is calling you to believe in your Lord and a pledge has been taken from you reading it as ukhidha mīthāqukum; otherwise akhadha mīthāqakum ‘He has taken a pledge from you’ concerning it — that is to say God took this pledge from you in the world of atoms when He made them bear witness against themselves ‘Am I not your Lord?’ They said ‘Yea indeed’ Q. 7172 — if you are believers? that is to say if your intention is to believe in Him then apply yourselves to this duty of faith.
