Sura Āl-ʿImrān 3:179

مَّا كَانَ ٱللَّـهُ لِيَذَرَ ٱلْمُؤْمِنِينَ عَلَىٰ مَآ أَنتُمْ عَلَيْهِ حَتَّىٰ يَمِيزَ ٱلْخَبِيثَ مِنَ ٱلطَّيِّبِ وَمَا كَانَ ٱللَّـهُ لِيُطْلِعَكُمْ عَلَى ٱلْغَيْبِ وَلَٰكِنَّ ٱللَّـهَ يَجْتَبِى مِن رُّسُلِهِۦ مَن يَشَآءُ فَـَٔامِنُوا۟ بِٱللَّـهِ وَرُسُلِهِۦ وَإِن تُؤْمِنُوا۟ وَتَتَّقُوا۟ فَلَكُمْ أَجْرٌ عَظِيمٌ

mā kāna allāhu li-yadhara l-muʾminīna ʿalā mā antum ʿalayhi ḥattā yamīza l-khabītha mina l-ṭayyibi wa-mā kāna allāhu li-yuṭliʿakum ʿalā l-ghaybi wa-lākinna allāha yajtabī min rrusulihi man yashāʾu fa-āminū billāhi wa-rusulihi wa-in tūʾminū wa-tattaqū fa-lakum ajrun ʿaẓīmun

Allah will not leave the believers in the state in which ye are now, until He separates what is evil from what is good nor will He disclose to you the secrets of the Unseen. But He chooses of His Messengers (For the purpose) whom He pleases. So believe in Allah. And His messengers: And if ye believe and do right, ye have a reward without measure.
