O believers, expend of that wherewith We have provided you, before there comes a day wherein shall be neither traffick, nor friendship, nor intercession; and the unbelievers -- they are the evildoers. 254 Allah is He besides Whom there is no god, the Everliving, the Self-subsisting by Whom all subsist; slumber does not overtake Him nor sleep; whatever is in the heavens and whatever is in the earth is His; who is he that can intercede with Him but by His permission? He knows what is before them and what is behind them, and they cannot comprehend anything out of His knowledge except what He pleases, His knowledge extends over the heavens and the earth, and the preservation of them both tires Him not, and He is the Most High, the Great. 255 No constraint is there in the religion; surely rectitude hath become manifestly distinguished from the error. Whosoever then disbelieveth in the devil and believeth in Allah, hath of a surety rain hold of the firm cable whereof there is no giving way. And Allah is Hearing, Knowing. 256 God is the Guardian of the believers and it is He who takes them out of darkness into light. The Devil is the guardian of those who deny the Truth and he leads them from light to darkness. These are the dwellers of hell wherein they will live forever. 257
