Quran

 3:179

مَا كَانَ اللَّهُ لِيَذَرَ الْمُؤْمِنِينَ عَلَىٰ مَا أَنْتُمْ عَلَيْهِ حَتَّىٰ يَمِيزَ الْخَبِيثَ مِنَ الطَّيِّبِ ۗ وَمَا كَانَ اللَّهُ لِيُطْلِعَكُمْ عَلَى الْغَيْبِ وَلَٰكِنَّ اللَّهَ يَجْتَبِي مِنْ رُسُلِهِ مَنْ يَشَاءُ ۖ فَآمِنُوا بِاللَّهِ وَرُسُلِهِ ۚ وَإِنْ تُؤْمِنُوا وَتَتَّقُوا فَلَكُمْ أَجْرٌ عَظِيمٌ ﴿١٧٩﴾

179. Allah would not leave the believers as you are, without identifying the insincere from the sincere. Nor would Allah inform you about the future, but Allah chooses from among His messengers whom He wills. So believe in Allah and His messengers. And if you believe and protect yourselves, you will have a splendid reward.
