And they ask you about the soul. Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but a little. 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!" 88 And We have explained to man, in this Qur'an, every kind of similitude: yet the greater part of men refuse (to receive it) except with ingratitude! 89 And they say: We will by no means believe in you until you cause a fountain to gush forth from the earth for us. 90 or that there be a garden of palms and vines for you and then you cause rivers to abundantly flow forth through them; 91 or cause the sky to fall into pieces on us - as you believe you can - or bring God and the angels face to face with us, 92 Or there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
