3:179
مَّا كَانَ ٱللَّهُ لِ يَذَرَ ٱلْ مُؤْمِنِينَ عَلَىٰ مَآ أَنتُمْ عَلَيْ هِ حَتَّىٰ يَمِيزَ ٱلْ خَبِيثَ مِنَ ٱل طَّيِّبِ وَ مَا كَانَ ٱللَّهُ لِ يُطْلِعَ كُمْ عَلَى ٱلْ غَيْبِ وَ لَٰكِنَّ ٱللَّهَ يَجْتَبِى مِن رُّسُلِ هِۦ مَن يَشَآءُ فَ ـَٔامِنُ وا۟ بِ ٱللَّهِ وَ رُسُلِ هِۦ وَ إِن تُؤْمِنُ وا۟ وَ تَتَّقُ وا۟ فَ لَ كُمْ 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.
