Surat Aal-i-Imraan (The Family of Imraan) - آل عمران

مَّا كَانَ ٱللَّهُ لِيَذَرَ ٱلْمُؤْمِنِينَ عَلَىٰ مَآ أَنتُمْ عَلَيْهِ حَتَّىٰ يَمِيزَ ٱلْخَبِيثَ مِنَ ٱلطَّيِّبِ وَمَا كَانَ ٱللَّهُ لِيُطْلِعَكُمْ عَلَى ٱلْغَيْبِ وَلَٰكِنَّ ٱللَّهَ يَجْتَبِى مِن رُّسُلِهِۦ مَن يَشَآءُ فَـَٔامِنُوا۟ بِٱللَّهِ وَرُسُلِهِۦ وَإِن تُؤْمِنُوا۟ وَتَتَّقُوا۟ فَلَكُمْ أَجْرٌ عَظِيمٌ ﴿١٧٩﴾

On no account will Allah leave the believers in the condition which you are in until He separates the evil from the good; nor is Allah going to make you acquainted with the unseen, but Allah chooses of His apostles whom He pleases; therefore believe in Allah and His apostles; and if you believe and guard (against evil), then you shall have a great reward.
