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 have other deities who can defend them against Us? They cannot even help themselves, neither can they be aided against Us. 43 We gave days of enjoyment to them and their fathers until their life became long. Are they unable to see how We come to their land and reduce its borders. Or, is it they who are the victors? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 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 And indeed We granted to Musa (Moses) and Harun (Aaron) the criterion (of right and wrong), and a shining light [i.e. the Taurat (Torah)] and a Reminder for Al-Muttaqun (the pious - see V. 2:2). 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 reminder that We have sent down. Will you then deny it? 50
