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 some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 Nay, We gave the luxuries 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 overcome. 44 SAY [unto all men]: "I but warn you on the strength of divine revelation!" But the deaf [of heart] will not hearken to this call, however often 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 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 We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 And this is a blessed Reminder which We have revealed; will you then deny it? 50
