Surah An Nahl Tafseer

Allah says:

إِنَّ الَّذِينَ لَا يُوْمِنُونَ بِأيَاتِ اللّهِ لَا يَهْدِيهِمُ اللّهُ وَلَهُمْ عَذَابٌ أَلِيمٌ

Verily, those who do not believe in Allah's Ayat (signs, or revelation), Allah will not guide them, and theirs will be a painful punishment.

Allah tells that He does not guide those who turn away from remembering Him and who are heedless of that which He revealed to His Messenger, those who have no intention of believing in that which he has brought from Allah. This kind of people will never be guided to faith by the signs of Allah and the Message which He sent His Messengers in this world, and they will suffer a painful and severe punishment in the Hereafter.

إِنَّمَا يَفْتَرِي الْكَذِبَ الَّذِينَ لَا يُوْمِنُونَ بِأيَاتِ اللّهِ وَأُوْلـيِكَ هُمُ الْكَاذِبُونَ
