ALI 'IMRAN — Ayat 179

مَّا كَانَ اللّهُ لِيَذَرَ الْمُؤْمِنِينَ عَلَى مَا أَنتُمْ عَلَيْهِ حَتَّىَ يَمِيزَ الْخَبِيثَ مِنَ الطَّيِّبِ وَمَا كَانَ اللّهُ لِيُطْلِعَكُمْ عَلَى الْغَيْبِ وَلَكِنَّ اللّهَ يَجْتَبِي مِن رُّسُلِهِ مَن يَشَاء فَآمِنُواْ بِاللّهِ وَرُسُلِهِ وَإِن تُؤْمِنُواْ وَتَتَّقُواْ فَلَكُمْ أَجْرٌ عَظِيمٌ

Allah would not leave the believers in that [state] you are in [presently] until He separates the evil from the good. Nor would Allah reveal to you the unseen. But [instead], Allah chooses of His messengers whom He wills, so believe in Allah and His messengers. And if you believe and fear Him, then for you is a great reward.
