Al-Baqarah 2:101

مَن كَانَ عَدُوًّا لِّلَّهِ وَمَلَائِكَتِهِ وَرُسُلِهِ وَجِبْرِيلَ وَمِيكَالَ فَإِنَّ اللَّهَ عَدُوٌّ لِّلْكَافِرِينَ

Whoever is an enemy to Allah and His angels and His messengers and Gabriel and Michael - then indeed, Allah is an enemy to the disbelievers.

وَلَقَدْ أَنزَلْنَا إِلَيْكَ آيَاتٍ بَيِّنَاتٍ ۖ وَمَا يَكْفُرُ بِهَا إِلَّا الْفَاسِقُونَ

And We have certainly revealed to you verses [which are] clear proofs, and no one would deny them except the defiantly disobedient.

أَوَكُلَّمَا عَاهَدُوا عَهْدًا نَّبَذَهُ فَرِيقٌ مِّنْهُم ۚ بَلْ أَكْثَرُهُمْ لَا يُؤْمِنُونَ

Is it not [true] that every time they took a covenant a party of them threw it away? But, [in fact], most of them do not believe.

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.
