تِلْكَ أُمَّةٌۭ قَدْ خَلَتْ ۖ لَهَا مَا كَسَبَتْ وَلَكُم مَّا كَسَبْتُمْ ۖ وَلَا تُسْـَٔلُونَ عَمَّا كَانُوا۟ يَعْمَلُونَ
That is a nation which has passed on. It will have [the consequence of] what it earned, and you will have what you have earned. And you will not be asked about what they used to do.
Say (O Muhammad ﷺ to the Jews and Christians), "Dispute you with us about Allah while He is our Lord and your Lord? And we are to be rewarded for our deeds and you for your deeds. And we are sincere to Him (i.e. we worship Him alone and none else, and we obey His orders). (139)Or say you that Ibrahim, Isma'il, Ishaq, Ya'qub and Al-Asbat, were Jews or Christians? Say, "Do you know better or does Allah? And who is more unjust than he who conceals the testimony he has from Allah? And Allah is not unaware of what you do. (140)That was a nation who has passed away. They shall receive the reward of what they earned, and you of what you earn. And you will not be asked of what they used to do (141)
Allah directed His Prophet ﷺ to pre-empt the arguments with the idolators:
قُلْ أَتُحَاجُّونَنَا فِي اللَّهِ
(Say (O Muhammad ﷺ to the Jews and Christians), "Dispute you with us about Allah) meaning, "Do you dispute with us regarding the Oneness of Allah, obedience and submission to Him and in avoiding His prohibitions,
وَهُوَ رَبُّنَا وَرَبُّكُمْ
(while He is our Lord and your Lord?) meaning, He has full control over us and you, and deserves the worship alone without partners.
وَلَنَا أَعْمَالُنَا وَلَكُمْ أَعْمَالُكُمْ
(And we are to be rewarded for our deeds and you for your deeds.) meaning, we disown you and what you worship, just as you disown us. Allah said in another Ayah,
وَإِن كَذَّبُوكَ فَقُل لِّي عَمَلِي وَلَكُمْ عَمَلُكُمْ ۖ أَنتُم بَرِيئُونَ مِمَّا أَعْمَلُ وَأَنَا بَرِيءٌ مِّمَّا تَعْمَلُونَ
(And if they belie you, say: "For me are my deeds and for you are your deeds! You are innocent of what I do, and I am innocent of what you do!")(10:41), and,
فَإِنْ حَاجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِيَ لِلَّهِ وَمَنِ اتَّبَعَنِ
(So if they dispute with you (Muhammad ﷺ) say: "I have submitted myself to Allah (in Islam), and (so have) those who follow me")(3:20). Allah said about Ibrahim,
وَحَاجَّهُ قَوْمُهُ قَالَ أَتُحَاجُّونِّي فِي اللَّهِ
(His people disputed with him. He said: "Do you dispute with me concerning Allah")(6:80), and,
أَلَمْ تَرَ إِلَى الَّذِي حَاجَّ إِبْرَاهِيمَ فِي رَبِّهِ
(Have you not looked at him who disputed with Ibrahim about his Lord (Allah)?)(2:258). He said in this honorable Ayah,
وَلَنَا أَعْمَالُنَا وَلَكُمْ أَعْمَالُكُمْ وَنَحْنُ لَهُ مُخْلِصُونَ
(And we are to be rewarded for our deeds and you for your deeds. And we are sincere to Him.) meaning, "We disown you just as you disown us,"
وَنَحْنُ لَهُ مُخْلِصُونَ
(And we are sincere to Him), in worship and submission.
Allah then criticized them in the claim that Ibrahim, the Prophets who came after him and the Asbat were following their religion, whether Judaism or Christianity. Allah said,
قُلْ أَأَنتُمْ أَعْلَمُ أَمِ اللَّهُ
(Say, "Do you know better or does Allah?") meaning, Allah has the best knowledge and He stated that they were neither Jews, nor Christians. Similarly, Allah said in the Ayah,
مَا كَانَ إِبْرَاهِيمُ يَهُودِيًّا وَلَا نَصْرَانِيًّا وَلَٰكِن كَانَ حَنِيفًا مُّسْلِمًا وَمَا كَانَ مِنَ الْمُشْرِكِينَ
(Ibrahim was neither a Jew nor a Christian, but he was a true Muslim Hanifa (to worship none but Allah alone) and he was not of …
