وَلَا تُؤْمِنُوا إِلَّا لِمَن تَبِعَ دِينَكُمْ قُلْ إِنَّ الْهُدَىٰ هُدَى اللَّهِ أَن يُؤْتَىٰ أَحَدٌ مِّثْلَ مَا أُوتِيتُمْ أَوْ يُحَاجُّوكُمْ عِندَ رَبِّكُمْ ۗ قُلْ إِنَّ الْفَضْلَ بِيَدِ اللَّهِ يُؤْتِيهِ مَن يَشَاءُ ۗ وَاللَّهُ وَاسِعٌ عَلِيمٌ ٧٣

And do not believe anyone but him who follows (only) your din (religion).’ Say: ‘Surely, the guidance is but the guidance of Allah (alone).’ (And they further say to their people never to believe even this) that: ‘The like of the Book (or din [religion]) given to you may also be given to anyone else, or that someone may give a plea against you before your Lord.’ Say: ‘Bounty is in the Hand of Allah; He bestows on whom He pleases and Allah is All-Embracing, All-Knowing. (3:73)
