2:256 لَآ إِكْرَاهَ فِى ٱلدِّينِ قَد تَّبَيَّنَ ٱلرُّشْدُ مِنَ ٱلْغَىِّ فَمَن يَكْفُرْ بِٱلطَّٰغُوتِ وَيُؤْمِنۢ بِٱللَّهِ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ لَا ٱنفِصَامَ لَهَا وَٱللَّهُ سَمِيعٌ عَلِيمٌ
There is no compulsion in religion; truly the right way has become clearly distinct from error; therefore, whoever disbelieves in the Shaitan and believes in Allah he indeed has laid hold on the firmest handle, which shall not break off, and Allah is Hearing, Knowing.
He said: As Thou hast caused me to remain disappointed I will certainly lie in wait for them in Thy straight path.
7:146 سَأَصْرِفُ عَنْ ءَايَٰتِىَ ٱلَّذِينَ يَتَكَبَّرُونَ فِى ٱلْأَرْضِ بِغَيْرِ ٱلْحَقِّ وَإِن يَرَوْا۟ كُلَّ ءَايَةٍ لَّا يُؤْمِنُوا۟ بِهَا وَإِن يَرَوْا۟ سَبِيلَ ٱلرُّشْدِ لَا يَتَّخِذُوهُ سَبِيلًا وَإِن يَرَوْا۟ سَبِيلَ ٱلْغَىِّ يَتَّخِذُوهُ سَبِيلًا ذَٰلِكَ بِأَنَّهُمْ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَكَانُوا۟ عَنْهَا غَٰفِلِينَ
I will turn away from My communications those who are unjustly proud in the earth; and if they see every sign they will not believe in It; and if they see the way of rectitude they do not take It for a way, and if they see the way of error. they take it for a way; this is because they rejected Our communications and were heedless of them.
7:175 وَٱتْلُ عَلَيْهِمْ نَبَأَ ٱلَّذِىٓ ءَاتَيْنَٰهُ ءَايَٰتِنَا فَٱنسَلَخَ مِنْهَا فَأَتْبَعَهُ ٱلشَّيْطَٰنُ فَكَانَ مِنَ ٱلْغَاوِينَ
And recite to them the narrative of him to whom We give Our communications, but he withdraws himself from them, so the Shaitan overtakes him, so he is of those who go astray.
And their brethren increase them in error, then they cease not.
11:34 وَلَا يَنفَعُكُمْ نُصْحِىٓ إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ ٱللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَ
And if I intend to give you good advice, my advice will not profit you if Allah intended that He should leave you to go astray; He is your Lord, and to Him shall you be returned.
15:39 قَالَ رَبِّ بِمَآ أَغْوَيْتَنِى لَأُزَيِّنَنَّ لَهُمْ فِى ٱلْأَرْضِ وَلَأُغْوِيَنَّهُمْ أَجْمَعِينَ
He said: My Lord! because Thou hast made life evil to me, I will certainly make (evil) fair-seeming to them on earth, and I will certainly cause them all to deviate
Surely. as regards My servants, you have no authority ,over them except those who follow you of the deviators.
19:59 فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ فَسَوْفَ يَلْقَوْنَ غَيًّا
But there came after them an evil generation, who neglected prayers and followed and sensual desires, so they win meet perdition,
20:121 فَأَكَلَا مِنْهَا فَبَدَتْ لَهُمَا سَوْءَٰتُهُمَا وَطَفِقَا يَخْصِفَانِ عَلَيْهِمَا مِن وَرَقِ ٱلْجَنَّةِ وَعَصَىٰٓ ءَادَمُ رَبَّهُۥ فَغَوَىٰ
Then they both ate of it, so their evil inclinations became manifest to them, and they both began to cover themselves with leaves of the garden, and Adam disobeyed his Lord, so his life became evil (to him).
And the hell shall be made manifest to the erring ones,
So they shall be thrown down into it, they and the erring ones,
And as to the poets, those who go astray follow them.
28:18 فَأَصْبَحَ فِى ٱلْمَدِينَةِ خَآئِفًا يَتَرَقَّبُ فَإِذَا ٱلَّذِى ٱسْتَنصَرَهُۥ بِٱلْأَمْسِ يَسْتَصْرِخُهُۥ قَالَ لَهُۥ مُوسَىٰٓ إِنَّكَ لَغَوِىٌّ مُّبِينٌ
And he was in the city, fearing, awaiting, when lo! he who had asked his assistance the day before was crying out to him for aid. Musa said to him: You are most surely one erring manifestly.
28:63 قَالَ ٱلَّذِينَ حَقَّ عَلَيْهِمُ ٱلْقَوْلُ رَبَّنَا هَٰٓؤُلَآءِ ٱلَّذِينَ أَغْوَيْنَآ أَغْوَيْنَٰهُمْ كَمَا غَوَيْنَا تَبَرَّأْنَآ إِلَيْكَ مَا كَانُوٓا۟ إِيَّانَا يَعْبُدُونَ
Those against whom the sentence has become confirmed will say: Our Lord! these are they whom we caused to err; we caused them to err as we ourselves did err; to Thee we declare ourselves to be clear (of them); they never served Us.
So we led you astray, for we ourselves were erring.
He said: Then by Thy Might I will surely make them live an evil life, all,
Your companion does not err, nor does he go astray;
