We did indeed aforetime give the Book to Moses: be not then in doubt of its reaching (thee): and We made it a guide to the Children of Israel. 23 And We made from among them leaders guiding by Our command when they were patient and [when] they were certain of Our signs. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 25 Is it not a guidance for them (to observe) how many generations We destroyed before them, amid whose dwelling places they do walk? Lo! therein verily are portents! Will they not then heed? 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 Say, "On the day of the final triumph, the faith of the disbelievers will be of no avail to them, nor will they be given any respite". 29 and then leave them alone, and wait [for the truth to unfold as] they, behold, are waiting. 30
