The Letter Qaf - 50:26 He who has taken other gods along with Allah. Throw him into the severe punishment.
In the context of verses 20, 21...30; on the Day of Resurrection, the soul of the human being and the soul of the devil, whom he has made his friend and sovereign, are matched/identified, take their final form and are thrown into hell:

The Cattle/6:128 "On the Day when He will gather them all together: "O people of the jinn, you have wasted a great number of men". Their friends from among mankind: "Our Lord, we enjoyed each other until we reached the end of the term You gave us". He will say: "Your abode is the Fire."They will abide therein forever, except Allah wills. Your Lord is Wise, Knowing."
The Cattle/6:129 Thus do We pair the wrongdoers and make them each other´s friends. Because of what they used to do.
The Cattle/6:130 "O people of the jinn and mankind, have not messengers come to you from you, telling you My Verses and warning you of this Day? They said: "We are witnesses against ourselves". The life of this world deceived them and they testified against themselves that they were disbelievers."

The Prophets/21:98 You and those whom you serve besides Allah are the fuel of Hell; you are worthy to enter it.

Those Who Set The Ranks/37:19 It is a single touch. Then they (get up and) look.
Those Who Set The Ranks/37:20 "Woe to us!"they say, "This is the Day of Judgment."
Those Who Set The Ranks/37:21 This is the Day of Judgment which you have denied.
Those Who Set The Ranks/37:22 Gather the wrongdoers. Their wives and
Those Who Set The Ranks/37:23 Those whom they serve besides Allah. Show them the way to Hell.
Those Who Set The Ranks/37:24 And stop them; they will be questioned.
Those Who Set The Ranks/37:26 No, on that Day they will have surrendered completely.
Those Who Set The Ranks/37:27 They will turn and question one another.
Those Who Set The Ranks/37:28 "They will say: "You were approaching us from our right side"."
Those Who Set The Ranks/37:29 "They will say, "Indeed you were not believers"."
Those Who Set The Ranks/37:30 We had no power over you. On the contrary, you were a people who were in a wicked state.
Those Who Set The Ranks/37:31 The Word of our Lord about us has come true, so we shall taste.
Those Who Set The Ranks/37:32 We were the wicked, so We made you wicked.
Those Who Set The Ranks/37:33 So on that Day they will be partners in the torment.
Those Who Set The Ranks/37:34 This is what We do to the guilty.

The Letter Qaf/50:20 The trumpet has been blown. This is the promised Day.
The Letter Qaf/50:21 Every soul comes with a driver and a witness.
The Letter Qaf/50:22 You were completely oblivious of this. Now We have lifted your veil; today your eye is sharp as steel.
The Letter Qaf/50:23 "His companion will say, "Here is my companion ready."
The Letter Qaf/50:24 Let the two of you cast into hell every stubborn disbeliever,
The Letter Qaf/50:25 The one who hinders the good, the violent, the skeptic.
The Letter Qaf/50:26 He who has taken other gods along with Allah. Throw him into the severe punishment.
The Letter Qaf/50:27 "His companion says, "My Lord, I did not tempt him, but he was in deep error."
The Letter Qaf/50:28 "He says, "Do not quarrel in My presence. I have already sent you a warning."
The Letter Qaf/50:29 "He says: "In My Presence the word is not changed, and I never wrong the servants."
The Letter Qaf/50:30 "On that Day We shall say to Hell, "Are you full?"It will say, "Are you full yet?"

The Banishment/59:15 They are like those who passed away a little while before them. They tasted the recompense of what they used to do and deserved a painful torment.
The Banishment/59:16 "They are just like Satan: He says to man, "Deny". Then when he disbelieves, he says, "I have nothing to do with you. I fear Allah, the Lord of the universes."
The Banishment/59:17 They both ended up in the Fire where they will abide forever. Such is the punishment of the wrongdoers.
