Say: Who guardeth you in the night or in the day from the Beneficent? Nay, but they turn away from mention of their Lord! 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 Nay, We generously provided them and their fathers, and they enjoyed Our provision for long. Do they not see that We are now advancing into their territory, diminishing it from different sides? Is it they, then, who will triumph?" 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing 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 We shall maintain proper justice on the Day of Judgment. No soul will be wronged the least. For a deed even as small as a mustard seed one will duly be recompensed. We are efficient in maintaining the account. 47 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 those who fear Allah in the Unseen, tremble because of the Hour. 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
