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 from among them leaders guiding by Our command when they were patient and [when] they were certain of Our signs. 24 Surely your Lord will decide between them about what they were at variance, on the Day of Resurrection. 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 drive the water to the dry land and bring forth crops therewith whereof their cattle and themselves eat? What, will they not see? 27 They say: "When will this decision be, if ye are telling the truth?" 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 So turn aside from them (O Muhammad SAW) and await, verily they (too) are awaiting. 30
