Abbas - Tanwîr al-Miqbâs min Tafsîr Ibn ‘Abbâs
The disbelievers answer back and say: “you have indeed commanded us to worship”, at which point the idols respond: (Allah sufficeth as a witness between us and you, that we were unaware of your worship) we were ignorant of your worship of us.
(then We shall say to those who did associate partners: "Stop at your place! You and your partners.'') He then will command the idolators to stay where they are and not to move from their destined places so they would be separated from the place of the believers. Similarly, Allah said:
وَامْتَازُواْ الْيَوْمَ أَيُّهَا الْمُجْرِمُونَ
((It will be said): "And O you the criminals! Get you apart this Day (from the believers).)(36:59) Allah also said:
(And on the Day when the Hour will be established - that Day shall (all men) be separated (the believers will be separated from the disbelievers). )30:14 In the same Surah, Ar-Rum, Allah said:
(On that Day men shall be divided.) 30:43 means, they shall be divided in two. This is what will take place when Allah Almighty will come for Final Judgement. The believers intercede to Allah so the Final Judgement may come and they get rid of that state. The Prophet said,
(And who is more astray than one who calls on (invokes) besides Allah, such as will not answer him till the Day of Resurrection, and who are (even) unaware of their calls (invocations) to them And when mankind are gathered (on the Day of Resurrection), they (false deities) will become their enemies)46:5-6. This refers to the partners responding to those who worshipped them, Then Allah said:
فَكَفَى بِاللَّهِ شَهِيدًا بَيْنَنَا وَبَيْنَكُمْ
(So sufficient is Allah as a witness between us and you.) They say that we did not know or think that you were worshipping us. Allah is a Witness between us and you that we never called upon you to worship us. We never ordered you to worship us; neither did we accept your worship of us. Allah said:
هُنَالِكَ تَبْلُواْ كُلُّ نَفْسٍ مَّآ أَسْلَفَتْ
(There! Every person will know (exactly) what he had earned before) This will be the state of accounting on the Day of Resurrection. Every soul shall know all that it had sent forth, both good and evil. Similarly, Allah said:
يَوْمَ تُبْلَى السَّرَآئِرُ
(The Day when all the secrets will be examined.)86:9,
(...and on the Day of Resurrection, We shall bring out for him a book which he will find wide open. (It will be said to him): "Read your book. You yourself are sufficient as a reckoner against you this Day.'') 17:13-14 Then Allah said,
وَرُدُّواْ إِلَى اللَّهِ مَوْلَـهُمُ الْحَقِّ
(and they will be brought back to Allah, their rightful Mawla.) All affairs and matters will be brought back to Allah, the Judge, the All-Just. He will judge everyone, and then admit the people of Paradise in Paradise and the people of Hell to Hell.
(and will vanish from them) meaning what the idolators worshipped,
مَّا كَانُواْ يَفْتَرُونَ
(what they invented) what they worshipped besides Allah that they invented.
Maududi - Sayyid Abul Ala Maududi - Tafhim al-Qur'an
That is, "Their deities-the angels, the jinns, the spirits, the forefathers, the prophets, the saints, the martyrs and all others-whom they had set up as partners with God and rendered those rights to them which belonged to God alone, will dissociate themselves from their worshipers and declare, "We did not know at all that you worshiped us, for no reverence, no respect, no honor, no admiration, no regard, no adoration, no homage, that you paid to us; no prayer, no supplication, no request, no offering, no gift, you presented to us; and no praise, no prostration, no bowing down, no remembrance, no religious service, or ceremony or ritual you made in our name ever reached us."
