The idolaters say: 'Had Allah willed, neither we nor our fathers would have worshipped anything other than Him, nor would we have forbidden anything without Him', as such did those before them. Yet what should Messengers do but give a clear deliverance? 35 For We assuredly sent amongst every People a messenger, (with the Command), "Serve Allah, and eschew Evil": of the People were some whom Allah guided, and some on whom error became inevitably (established).

Yea! it is a promise on Him incumbent but most of mankind know not. 38 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Verily! Our Word unto a thing when We intend it, is only that We say unto it: "Be!" and it is. 40
