Assuredly We vouchsafed the Book unto Musa; so be thou not in doubt in thy receiving it. And We appointed it to be a guidance unto the Children of Is'rail. 23 And We made of them Imams to guide by Our command when they were patient, and they were certain of Our communications. 24 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 25 [But] can, then, they [who deny the truth] learn no lesson by recalling how many a generation We have destroyed before their time? [people] in whose dwelling-places they [themselves now] walk about? In this, behold, there are messages indeed: will they not, then, listen? 26 And do they not see that We send the water to the barren land and produce crops with it, so their animals and they themselves eat from it? So do they not perceive? 27 And they say: When will this Decision arrive if ye are truthtellers? 28 Tell them: “If the unbelievers were to believe on the Day of Judgement that will not avail them. For then they will be granted no respite.” 29 Therefore turn away from them and wait, surely they too are waiting. 30
