إِنَّهُمْ إِن يَظْهَرُوا۟ عَلَيْكُمْ يَرْجُمُوكُمْ أَوْ يُعِيدُوكُمْ فِى مِلَّتِهِمْ وَلَن تُفْلِحُوٓا۟ إِذًا أَبَدًا
Innahum iny yazharoo 'alaikum yarjumookum aw yu'eedookum fee millatihim wa lan tuflihooo izan abadaa
If they discover you, they will stone you or force you back into their way of life, and then you would never succeed, ever.
