Aya number 23 of surat Al-Anfal
بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
وَلَوْ عَلِمَ اللَّهُ فِيهِمْ خَيْرًا لَأَسْمَعَهُمْ وَلَوْ أَسْمَعَهُمْ لَتَوَلَّوْا وَهُمْ مُعْرِضُونَ 
Translation: English - Sahih International
Had Allah known any good in them, He would have made them hear. And if He had made them hear, they would [still] have turned away, while they were refusing.
