Al-A‘râf 7:186
مَن يُضْلِلِ اللَّهُ فَلَا هَادِيَ لَهُ ۚ وَيَذَرُهُمْ فِي طُغْيَانِهِمْ يَعْمَهُونَ ١٨٦
Man yudlili Allahu fala hadiya lahu wayatharuhum fee tughyanihim yaAAmahoona
“Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy.” (7:186)
وَمَن يُرِدِ اللَّهُ فِتْنَتَهُ فَلَن تَمْلِكَ لَهُ مِنَ اللَّهِ شَيْئاً
(And whomsoever Allah wants to put in Fitnah (error, because of his rejecting of Faith, or trial), you can do nothing for him against Allah) 5:41, and,
قُلِ انظُرُواْ مَاذَا فِى السَّمَـوَتِ وَالاٌّرْضِ وَمَا تُغْنِى الآيَـتُ وَالنُّذُرُ عَن قَوْمٍ لاَّ يُؤْمِنُونَ
(Say: "Behold all that is in the heavens and the earth," but neither Ayat nor warners benefit those who believe not) 10:101.
