Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Or, have they gods who can defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 Nay, We gave provision to these and their fathers until life was prolonged to them. Do they not then see that We are visiting the land, curtailing it of its sides? Shall they then prevail? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, we were evildoers!" 46 And We will set up a just balance on the day of resurrection, so no soul shall be dealt with unjustly in the least; and though there be the weight of a grain of mustard seed, (yet) will We bring it, and sufficient are We to take account. 47 And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil). 48 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
