وَمَن يَرْغَبُ عَن مِّلَّةِ إِبْرَٰهِۦمَ إِلَّا مَن سَفِهَ نَفْسَهُۥ ۚ وَلَقَدِ ٱصْطَفَيْنَٰهُ فِى ٱلدُّنْيَا ۖ وَإِنَّهُۥ فِى ٱلْءَاخِرَةِ لَمِنَ ٱلصَّٰلِحِينَ
And who forsaketh the religion of Abraham save him who befooleth himself? Verily We chose him in the world, and lo! in the Hereafter he is among the righteous.
