قُلۡ أَتُحَآجُّونَنَا فِي ٱللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمۡ وَلَنَآ أَعۡمَٰلُنَا وَلَكُمۡ أَعۡمَٰلُكُمۡ وَنَحۡنُ لَهُۥ مُخۡلِصُونَ ١٣٩
Say, [O Muḥammad], "Do you argue with us about Allāh while He is our Lord and your Lord? For us are our deeds, and for you are your deeds. And we are sincere [in deed and intention] to Him."
Translation: Saheeh International (English)
Each word's meaning and sound
If the People of the Scripture argue with you, saying they have more right to Allah and His religion than you do because their way of life is older and their scriptures came before yours, then it will not benefit them. Allah is the Lord of everyone, and He is not for them alone. Tell them, O Prophet, that you have your actions which they will not be asked about; and they have their actions which you will not be asked about. Everyone will be rewarded according to what they have done. Tell them that you are sincere to Allah in your worship and in doing as He instructs you, and that you do not worship anything apart from Him.
