Allah condemns the idolators for taking intercessors besides Allah, namely the idols and false gods whom they have taken on the basis of their own whims, with no evidence or proof. These idols are not able to do anything; they have no minds with which to think, and they cannot hear or see. They are inanimate and are much worse off than animals. Then Allah says: `Say -- O Muhammad -- to these people who claim that those whom they have taken as intercessors with Allah, that intercession is of no avail except for the one with whom Allah is pleased and to whom He has granted permission to intercede. The whole matter rests with Him.'
(Who is he that can intercede with Him except with His permission) (2:255).
(His is the sovereignty of the heavens and the earth.) means, He is the One Who is in control of all that.
(Then to Him you shall be brought back.) means, `on the Day of Resurrection, then He will judge between you with His justice, and He will reward or punish each person according to his deeds.' Then Allah condemns the idolators further:
(And when Allah Alone is mentioned) means, when it is said there is no (true) God except Allah Alone,
(the hearts of those who believe not in the Hereafter are filled with disgust) Mujahid said, "Their hearts are filled with disgust means they recoil in horror." This is like the Ayah:
(Truly, when it was said to them: "La ilaha illa Allah," they puffed themselves up with pride.) (37:35) which means, they were too proud to follow it. Their hearts could not accept anything good, and whoever cannot accept good will accept evil. Allah says:
(and when those besides Him are mentioned,) meaning, the idols and false gods -- this was the view of Mujahid --
(behold, they rejoice!) means, they feel happy.
