What keeps people from belief that guidance has come to them, but they question, "Why has God sent a mortal Messenger?" 94 (Muhammad), say, "Had the earth been inhabited by angels who would walk serenely therein, only then would We have sent to them angelic Messengers". 95 Say: 'Allah is sufficient as a witness between me and you. He knows and observes His worshipers' 96 Those whom Allah guides are rightly guided; but for those whom He leads astray you shall find no guardian, other than Him. On the Day of Resurrection We shall gather all of them upon their faces, blind, dumb, deaf. Gehenna shall be their refuge, whenever it dwindles, We will increase the Blaze for them. 97 Such will be their requital for having rejected Our messages and having said, "After we will have become bones and dust, shall we, forsooth, be raised from the dead in a new act of creation?" 98 ۞ See they not that Allah, Who created the heavens and the earth, has power to create the like of them (anew)? Only He has decreed a term appointed, of which there is no doubt. But the unjust refuse (to receive it) except with ingratitude. 99 Say: 'If you possessed the treasuries of my Lord's mercy, yet would you hold back for fear of expending; and man is ever niggardly.' 100
