Your property and children cannot bring you closer to Us. Only those who believe and act righteously will have double reward for their deeds and will live in secure mansions. 37 And those who endeavour to frustrate Our signs, unto the torment they will be brought. 38 Say thou: verily my Lord expandeth the provision for whomsoever He listeth of His bondmen, and stinteth it for him. And whatsoever ye expend of aught He shall replace it. And He is the Best of Providers. 39 Upon the day when He shall muster them all together, then He shall say to the angels, 'Was it you these were serving? 40 They shall say: Glory be to Thee! Thou art our Guardian, not they; nay! they worshipped the jinn; most of them were believers in them. 41 Today none of you has the power to benefit or harm another; and We shall say to the evil-doers: “Taste now the chastisement of the Fire which you used to deny, calling it a lie.” 42 For [thus it is:] whenever Our messages are conveyed unto them in all their clarity, they [who are bent on denying the truth] say [to one another,] "This [Muhammad] is nothing but a man who wants to turn you away from what your forefathers were wont to worship!" And they say: "This [Qur'an] is nothing but a falsehood invented [by man]!" And [finally,] they who are bent on denying the truth speak thus of the truth when it comes to them: "This is clearly nothing but spellbinding eloquence!" 43 We had not given them books to study, nor have We sent them a warner before you. 44 Their predecessors also rejected the truth. These have not attained to one tenth of the power that We had bestowed upon the earlier people. But they rejected My messengers. Then how terrible, was My chastisement! 45
