Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord. 42 Can their gods protect them against Us? Their gods have no power even to help themselves, nor are they safe from Our retribution. 43 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 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 To Moses and Aaron We granted the criteria of discerning right from wrong, and We gave them the light and a reminder to the pious ones 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 This is a Blessed Admonition that We have revealed. Are you, then, going to reject it? 50
