مَّا كَانَ ٱللَّهُ لِيَذَرَ ٱلْمُؤْمِنِينَ عَلَىٰ مَآ أَنتُمْ عَلَيْهِ حَتَّىٰ يَمِيزَ ٱلْخَبِيثَ مِنَ ٱلطَّيِّبِۗ وَمَا كَانَ ٱللَّهُ لِيُطْلِعَكُمْ عَلَى ٱلْغَيْبِ وَلَـٰكِنَّ ٱللَّهَ يَجْتَبِى مِن رُّسُلِهِۦ مَن يَشَآءُۖ فَـَٔـامِنُواْ بِٱللَّهِ وَرُسُلِهِۦۚ وَإِن تُؤْمِنُواْ وَتَتَّقُواْ فَلَكُمْ أَجْرٌ عَظِيمٌ ١٧٩
It is not (the purpose) of Allah to leave you in your present state till He shall separate the wicked from the good. And it is not (the purpose of) Allah to let you know the Unseen. But Allah chooseth of His messengers whom He will, (to receive knowledge thereof). So believe in Allah and His messengers. If ye believe and ward off (evil), yours will be a vast reward.
