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 some leaders among them, guiding by Our command, when they had persevered; and they used to accept faith in Our signs. 24 Your Lord will issue His decree about their (believers and disbeliever's) differences on the Day of Judgment. 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 Have they not seen how We lead the water to the barren land and therewith bring forth crops whereof their cattle eat, and they themselves? Will they not then see? 27 They also say, 'When shall be this Victory, if you speak truly?' 28 Say thou: on the day of the Decision their belief will not profit those who have disbelieved; nor will they be respited. 29 So turn thou away from them, and wait; they too are waiting. 30
