Say: "Who can guard and protect you in the night or in the day from the (punishment of the) Most Beneficent (Allah)?" Nay, but they turn away from the remembrance of their Lord. 42 Or do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected from Us. 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 revelation; and the deaf do not hear the call whenever they are warned. 45 And if a breath of the torment of thy Lord were to touch them, they will say: woe unto us! we have been wrong-doers. 46 We shall fix the scales of justice on the Day of Resurrection, so that none will be wronged in the least; and even if it were equal to a mustard seed in weight We shall take it (into account). We are sufficient for computation. 47 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
