Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 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 Nay, We gave the good things of this life to these men and their fathers until the period grew long for them; See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will win? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, we were evildoers!" 46 And We will set up a just balance on the day of resurrection, so no soul shall be dealt with unjustly in the least; and though there be the weight of a grain of mustard seed, (yet) will We bring it, and sufficient are We to take 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 the unseen, also dread the Hour of Judgement. 49 And this is a blessed Reminder which We have revealed; will you then deny it? 50
