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 Have they gods who defend them beside Us? They are not able to succour themselves, and against Us they cannot be kept company with. 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 yet if even a breath of your Lord's punishment touched them, they would say, "Woe to us! We were indeed wrongdoers." 46 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 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 Who are fearful of their Lord inwardly and dread the Hour. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
