Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Or have they gods that shall defend them apart from Us? Why, they are not able to help themselves, nor shall they be guarded in safety 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 (O Muhammad SAW): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [(i.e. one should follow only the Quran and the Sunnah (legal ways, orders, acts of worship, statements of Prophet Muhammad SAW, as the Companions of the Prophet SAW did)]. 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 set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners. 47 Surely We had granted to Moses and Aaron the Criterion (between right and wrong), and Light and Admonition for the good of the God-fearing, 48 who fear their unseen Lord and are anxious about the Day of Judgment. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
