His favours towards you has been great indeed. 87 Proclaim, “If all mankind and jinns agree to bring an equivalent to the Qur’an, they will not be able to bring its equal – even if they were to help each other.” 88 We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief. 89 And they say: We will not put faith in thee till thou cause a spring to gush forth from the earth for us; 90 or you have a garden of date palms and vines, and cause streams to flow plentifully in the midst of them; 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you bring Allah and the angels before (us) face to face; 92 or till thou possessest a house of gold ornament, or till thou goest up into heaven; and we will not believe thy going up till thou bringest down on us a book that we may read. Say: 'Glory be to my Lord. Am I aught but a mortal, a Messenger?' 93
