Al 'Imran, 179 Ayah
3:179
مَّا كَانَ ٱللَّهُ لِيَذَرَ ٱلۡمُؤۡمِنِينَ عَلَىٰ مَآ أَنتُمۡ عَلَيۡهِ حَتَّىٰ يَمِيزَ ٱلۡخَبِيثَ مِنَ ٱلطَّيِّبِۗ وَمَا كَانَ ٱللَّهُ لِيُطۡلِعَكُمۡ عَلَى ٱلۡغَيۡبِ وَلَٰكِنَّ ٱللَّهَ يَجۡتَبِي مِن رُّسُلِهِۦ مَن يَشَآءُۖ فَـَٔامِنُواْ بِٱللَّهِ وَرُسُلِهِۦۚ وَإِن تُؤۡمِنُواْ وَتَتَّقُواْ فَلَكُمۡ أَجۡرٌ عَظِيمٞ ١٧٩
Mā Kāna Al-Lahu Liyadhara Al-Mu'uminīna `Alá Mā 'Antum `Alayhi Ĥattá Yamīza Al-Khabītha Mina Aţ-Ţayyibi ۗ Wa Mā Kāna Al-Lahu Liyuţli`akum `Alá Al-Ghaybi Wa Lakinna Al-Laha Yajtabī Min Rusulihi Man Yashā'u ۖ Fa'āminū Bil-Lahi Wa Rusulihi ۚ Wa 'In Tu'uminū Wa Tattaqū Falakum 'Ajrun `Ažīmun
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.
