Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Do they [really think that they] have deities that could shield them from Us? Those [alleged deities] are not [even] able to succour themselves: hence, neither can they [who worship them hope to] be aided [by them] against 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 (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned. 45 Even if a whiff of the Lord's chastisement were to touch them they would surely say: "Ah woe, alas, we were surely sinful." 46 And We shall set up the scales of justice on the Day of Resurrection – therefore no soul will be wronged in the least; and if a thing is equal to a grain of mustard seed, We will bring it; and We are Sufficient 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 their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
