Al-Baqarah 2:105

وَاتَّبَعُوا مَا تَتْلُو الشَّيَاطِينُ عَلَىٰ مُلْكِ سُلَيْمَانَ ۖ وَمَا كَفَرَ سُلَيْمَانُ وَلَـٰكِنَّ الشَّيَاطِينَ كَفَرُوا يُعَلِّمُونَ النَّاسَ السِّحْرَ وَمَا أُنزِلَ عَلَى الْمَلَكَيْنِ بِبَابِلَ هَارُوتَ وَمَارُوتَ ۚ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّىٰ يَقُولَا إِنَّمَا نَحْنُ فِتْنَةٌ فَلَا تَكْفُرْ ۖ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِ بَيْنَ الْمَرْءِ وَزَوْجِهِ ۚ وَمَا هُم بِضَارِّينَ بِهِ مِنْ أَحَدٍ إِلَّا بِإِذْنِ اللَّهِ ۚ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ ۚ وَلَقَدْ عَلِمُوا لَمَنِ اشْتَرَاهُ مَا لَهُ فِي الْآخِرَةِ مِنْ خَلَاقٍ ۚ وَلَبِئْسَ مَا شَرَوْا بِهِ أَنفُسَهُمْ ۚ لَوْ كَانُوا يَعْلَمُونَ

And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Harut and Marut. But the two angels do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allah. And the people learn what harms them and does not benefit them. But the Children of Israel certainly knew that whoever purchased the magic would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew.

وَلَوْ أَنَّهُمْ آمَنُوا وَاتَّقَوْا لَمَثُوبَةٌ مِّنْ عِندِ اللَّهِ خَيْرٌ ۖ لَّوْ كَانُوا يَعْلَمُونَ

And if they had believed and feared Allah, then the reward from Allah would have been [far] better, if they only knew.

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَقُولُوا رَاعِنَا وَقُولُوا انظُرْنَا وَاسْمَعُوا ۗ وَلِلْكَافِرِينَ عَذَابٌ أَلِيمٌ

O you who have believed, say not [to Allah 's Messenger], "Ra'ina" but say, "Unthurna" and listen. And for the disbelievers is a painful punishment.

مَا نَنسَخْ مِنْ آيَةٍ أَوْ نُنسِهَا نَأْتِ بِخَيْرٍ مِّنْهَا أَوْ مِثْلِهَا ۗ أَلَمْ تَعْلَمْ أَنَّ اللَّهَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ

We do not abrogate a verse or cause it to be forgotten except that We bring forth [one] better than it or similar to it. Do you not know that Allah is over all things competent?

أَلَمْ تَعْلَمْ أَنَّ اللَّهَ لَهُ مُلْكُ السَّمَاوَاتِ وَالْأَرْضِ ۗ وَمَا لَكُم مِّن دُونِ اللَّهِ مِن وَلِيٍّ وَلَا نَصِيرٍ

Do you not know that to Allah belongs the dominion of the heavens and the earth and [that] you have not besides Allah any protector or any helper?

أَمْ تُرِيدُونَ أَن تَسْأَلُوا رَسُولَكُمْ كَمَا سُئِلَ مُوسَىٰ مِن قَبْلُ ۗ وَمَن يَتَبَدَّلِ الْكُفْرَ بِالْإِيمَانِ فَقَدْ ضَلَّ سَوَاءَ السَّبِيلِ

Or do you intend to ask your Messenger as Moses was asked before? And whoever exchanges faith for disbelief has certainly strayed from the soundness of the way.
