Al-Baqarah 2:207

وَمِنَ النَّاسِ مَن يُعْجِبُكَ قَوْلُهُ فِي الْحَيَاةِ الدُّنْيَا وَيُشْهِدُ اللَّهَ عَلَىٰ مَا فِي قَلْبِهِ وَهُوَ أَلَدُّ الْخِصَامِ

And of the people is he whose speech pleases you in worldly life, and he calls Allah to witness as to what is in his heart, yet he is the fiercest of opponents.

وَإِذَا تَوَلَّىٰ سَعَىٰ فِي الْأَرْضِ لِيُفْسِدَ فِيهَا وَيُهْلِكَ الْحَرْثَ وَالنَّسْلَ ۗ وَاللَّهُ لَا يُحِبُّ الْفَسَادَ

And when he goes away, he strives throughout the land to cause corruption therein and destroy crops and animals. And Allah does not like corruption.

وَإِذَا قِيلَ لَهُ اتَّقِ اللَّهَ أَخَذَتْهُ الْعِزَّةُ بِالْإِثْمِ ۚ فَحَسْبُهُ جَهَنَّمُ ۚ وَلَبِئْسَ الْمِهَادُ

And when it is said to him, "Fear Allah," pride in the sin takes hold of him. Sufficient for him is Hellfire, and how wretched is the resting place.

يَا أَيُّهَا الَّذِينَ آمَنُوا ادْخُلُوا فِي السِّلْمِ كَافَّةً وَلَا تَتَّبِعُوا خُطُوَاتِ الشَّيْطَانِ ۚ إِنَّهُ لَكُمْ عَدُوٌّ مُّبِينٌ

O you who have believed, enter into Islam completely [and perfectly] and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy.

فَإِن زَلَلْتُم مِّن بَعْدِ مَا جَاءَتْكُمُ الْبَيِّنَاتُ فَاعْلَمُوا أَنَّ اللَّهَ عَزِيزٌ حَكِيمٌ

But if you deviate after clear proofs have come to you, then know that Allah is Exalted in Might and Wise.

هَلْ يَنظُرُونَ إِلَّا أَن يَأْتِيَهُمُ اللَّهُ فِي ظُلَلٍ مِّنَ الْغَمَامِ وَالْمَلَائِكَةُ وَقُضِيَ الْأَمْرُ ۚ وَإِلَى اللَّهِ تُرْجَعُ الْأُمُورُ

Do they await but that Allah should come to them in covers of clouds and the angels [as well] and the matter is [then] decided? And to Allah [all] matters are returned.
