۞ شَرَعَ لَكُم مِّنَ ٱلدِّينِ مَا وَصَّىٰ بِهِۦ نُوحًۭا وَٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ وَمَا وَصَّيْنَا بِهِۦٓ إِبْرَٰهِيمَ وَمُوسَىٰ وَعِيسَىٰٓ ۖ أَنْ أَقِيمُوا۟ ٱلدِّينَ وَلَا تَتَفَرَّقُوا۟ فِيهِ ۚ كَبُرَ عَلَى ٱلْمُشْرِكِينَ مَا تَدْعُوهُمْ إِلَيْهِ ۚ ٱللَّهُ يَجْتَبِىٓ إِلَيْهِ مَن يَشَآءُ وَيَهْدِىٓ إِلَيْهِ مَن يُنِيبُ
He hath ordained for you that religion which He commended unto Noah, and that which We inspire in thee (Muhammad), and that which We commended unto Abraham and Moses and Jesus, saying: Establish the religion, and be not divided therein. Dreadful for the idolaters is that unto which thou callest them. Allah chooseth for Himself whom He will, and guideth unto Himself him who turneth (toward Him).
Surah Ash-Shura(42:13)
