(3) And marry not women whom your fathers married,- except what is past: It was shameful and odious,- an abominable custom indeed.

(4) Say: "Come, I will rehearse what Allah hath (really) prohibited you from": Join not anything as equal with Him; be good to your parents; kill not your children on a plea of want;- We provide sustenance for you and for them;- come not nigh to shameful deeds. Whether open or secret; take not life, which Allah hath made sacred, except by way of justice and law: thus doth He command you, that ye may learn wisdom.

(5) When they do aught that is shameful, they say: "We found our fathers doing so"; and "Allah commanded us thus": Say: "Nay, Allah never commands what is shameful: do ye say of Allah what ye know not?"

(6) Say: the things that my Lord hath indeed forbidden are: shameful deeds, whether open or secret; sins and trespasses against truth or reason; assigning of partners to Allah, for which He hath given no authority; and saying things about Allah of which ye have no knowledge.

(7) And (with passion) did she desire him, and he would have desired her, but that he saw the evidence of his Lord: thus (did We order) that We might turn away from him (all) evil and shameful deeds: for he was one of Our servants, sincere and purified.

(8) Allah commands justice, the doing of good, and liberality to kith and kin, and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that ye may receive admonition.

(9) Nor come nigh to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils).

(10) O ye who believe! follow not Satan's footsteps: if any will follow the footsteps of Satan, he will (but) command what is shameful and wrong: and were it not for the grace and mercy of Allah on you, not one of you would ever have been pure: but Allah doth purify whom He pleases: and Allah is One Who hears and knows (all things).
