Overall meaning :
Almighty Allah states that there is no good in much of what people secretly talk about among themselves, except in the case of those who enjoin charity, kindness or reconciliation between people, promising an immense reward for those who do so.
Warning those who stubbornly oppose the Messenger, may Allah bless him and grant him peace, after the truth has become manifest to them and wilfully follow a path other than that of the faithful, the Almighty mentions that He will let them pursue the path they have chosen for themselves, making it seem fair to them to draw them towards destruction step by step, and then He will burn them in Hellfire—an evil destination indeed.
Then He affirms that He will not forgive those who worship others besides Him and die in that state, but He will forgive any lesser sins than that of ascribing divinity to others besides Him for whomever He wills, stating that those who worship others besides Him have strayed far away from the truth.
He then explains that the idolaters call upon idols besides Him to which they give female names. By calling upon them and worshipping them, Allah states, they in fact obey and call upon none but Satan, who rebelliously disobeyed his Creator, and His Creator consequently excluded him from His mercy. Satan then swore by Him, saying that he would take a certain fixed portion of His servants who would obey him and that he would lead them astray from the right path, fill them with vain desires so that they would worship false deities besides Allah and disobey Him, order them to slit the ears of livestock in idolatrous sacrifice and alter and distort Allah’s creation. Then the Almighty warns that those who obey and take Satan for a supporter rather than Allah have surely suffered a manifest loss, explaining that Satan makes false promises to those who obey him and fills them with vain desires, and asserting that Satan’s promises are nothing but delusion and that the abode of who obey him will be Hell, from which they find no escape.
As for those who believe and do righteous deeds, Allah will admit them into gardens beneath which rivers flow, in which they abide forever. Such is Allah’s true and unfailing promise to them, and no one is truer than Allah in what He says.
