Al-Baqarah (البقرة)
Chapter 2 - The Cow
فَإِنْ ءَامَنُوا۟ بِمِثْلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهْتَدَوا۟ ۖ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا هُمْ فِى شِقَاقٍۢ ۖ فَسَيَكْفِيكَهُمُ ٱللَّهُ ۚ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ
Fa in aamanoo bimisli maaa aamantum bihee faqadih tadaw wa in tawallaw fa innamaa hum fee shiqaaq; fasayakfeekahumul laah; wa Huwas Samee'ul Aleem
So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing.
Quran 2:137 - Surah Al-Baqarah
وَقَالُوا۟ كُونُوا۟ هُودًا أَوْ نَصَٰرَىٰ تَهْتَدُوا۟ ۗ قُلْ بَلْ مِلَّةَ إِبْرَٰهِۦمَ حَنِيفًۭا ۖ وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ
They say, "Be Jews or Christians [so] you will be guided." Say, "Rather, [we follow] the religion of Abraham, inclining toward truth, and he was not of the polytheists."
قُولُوٓا۟ ءَامَنَّا بِٱللَّهِ وَمَآ أُنزِلَ إِلَيْنَا وَمَآ أُنزِلَ إِلَىٰٓ إِبْرَٰهِۦمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطِ وَمَآ أُوتِىَ مُوسَىٰ وَعِيسَىٰ وَمَآ أُوتِىَ ٱلنَّبِيُّونَ مِن رَّبِّهِمْ لَا نُفَرِّقُ بَيْنَ أَحَدٍۢ مِّنْهُمْ وَنَحْنُ لَهُۥ مُسْلِمُونَ
Say, [O believers], "We have believed in Allah and what has been revealed to us and what has been revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [in submission] to Him."
فَإِنْ ءَامَنُوا۟ بِمِثْلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهْتَدَوا۟ ۖ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا هُمْ فِى شِقَاقٍۢ ۖ فَسَيَكْفِيكَهُمُ ٱللَّهُ ۚ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ
So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing.
صِبْغَةَ ٱللَّهِ ۖ وَمَنْ أَحْسَنُ مِنَ ٱللَّهِ صِبْغَةًۭ ۖ وَنَحْنُ لَهُۥ عَٰبِدُونَ
[And say, "Ours is] the religion of Allah. And who is better than Allah in [ordaining] religion? And we are worshippers of Him."
قُلْ أَتُحَآجُّونَنَا فِى ٱللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمْ وَلَنَآ أَعْمَٰلُنَا وَلَكُمْ أَعْمَٰلُكُمْ 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."
