Qur'ān 2:139 · Al-Baqarah (البقرة)

قُلْ أَتُحَآجُّونَنَا فِى ٱللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمْ وَلَنَآ أَعْمَـٰلُنَا وَلَكُمْ أَعْمَـٰلُكُمْ وَنَحْنُ لَهُۥ مُخْلِصُونَ

Say, [O Muhammad], "Do you argue with us about Allah 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."
