Surah Fatir, Verse 5:
يَا أَيُّهَا النَّاسُ إِنَّ وَعْدَ اللَّهِ حَقٌّ فَلَا تَغُرَّنَّكُمُ الْحَيَاةُ الدُّنْيَا وَلَا يَغُرَّنَّكُم بِاللَّهِ الْغَرُورُ
O mankind! Verily, the Promise of Allah is true. So let not this present life deceive you, and let not the chief deceiver (Satan) deceive you about Allah.
Surah Fatir, Verse 6:
إِنَّ الشَّيْطَانَ لَكُمْ عَدُوٌّ فَاتَّخِذُوهُ عَدُوًّا إِنَّمَا يَدْعُو حِزْبَهُ لِيَكُونُوا مِنْ أَصْحَابِ السَّعِيرِ
Surely, Shaitan (Satan) is an enemy to you, so take (treat) him as an enemy. He only invites his Hizb (followers) that they may become the dwellers of the blazing Fire.
(English – Mohsin Khan)
