In this way...

In this way, in response to the believers of the Bible, who regard Judaism or Christianity as the only way of salvation, the Quran lays emphasis on the vast Islamic faith as the cause of man's salvation: وَقَالُوا كُونُوا هُودًا أَوْ نَصَارَىٰ تَهْتَدُوا ۗ قُلْ بَلْ مِلَّةَ إِبْرَاهِيمَ حَنِيفًا ۖ وَمَا كَانَ مِنَ الْمُشْرِكِينَ قُولُوا آمَنَّا بِاللَّهِ وَمَا أُنْزِلَ إِلَيْنَا وَمَا أُنْزِلَ إِلَىٰ إِبْرَاهِيمَ وَإِسْمَاعِيلَ وَإِسْحَاقَ وَيَعْقُوبَ وَالْأَسْبَاطِ وَمَا أُوتِيَ مُوسَىٰ وَعِيسَىٰ وَمَا أُوتِيَ النَّبِيُّونَ مِنْ رَبِّهِمْ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِنْهُمْ وَنَحْنُ لَهُ مُسْلِمُونَ Say you: "We believe in God, and in that which has been sent down on us and sent down on Abraham, Ismael, Isaac and Jacob, and the tribes, and that which was given to Moses and Jesus and the prophets, of their Lord; we make no distinction between any of them, and to Him we surrender.

It is so outstanding that the Qur'an has specifically emphasized on it, saying: آمَنَ الرَّسُولُ بِمَا أُنْزِلَ إِلَيْهِ مِنْ رَبِّهِ وَالْمُؤْمِنُونَ ۚ كُلٌّ آمَنَ بِاللَّهِ وَمَلَائِكَتِهِ وَكُتُبِهِ وَرُسُلِهِ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِنْ رُسُلِهِ ۚ وَقَالُوا سَمِعْنَا وَأَطَعْنَا ۖ غُفْرَانَكَ رَبَّنَا وَإِلَيْكَ الْمَصِيرُ The Messenger believes in what was sent down to him from his Lord, and (so do) the believers; each one believes in God and His angels, and in His Books and His messengers; we make no distinction between anyone of His messengers.
