The Holy Quran, Chapter Al-Muddathth - المدّثر

قَالُوا لَمْ نَكُ مِنَ الْمُصَلِّينَ

They will answer: We were not of those who prayed

عَنِ الْمُجْرِمِينَ

Concerning the guilty:

إِلَّا أَصْحَابَ الْيَمِينِ

Save these who will stand on the right hand.

لِمَن شَاء مِنكُمْ أَن يَتَقَدَّمَ أَوْ يَتَأَخَّرَ

Unto him of you who will advance or hang back.

إِنَّهَا لَإِحْدَى الْكُبَرِ

Lo! this is one of the greatest (portents)

وَاللَّيْلِ إِذْ أَدْبَرَ

And the night when it withdraweth

وَمَا جَعَلْنَا أَصْحَابَ النَّارِ إِلَّا مَلَائِكَةً وَمَا جَعَلْنَا عِدَّتَهُمْ إِلَّا فِتْنَةً لِّلَّذِينَ كَفَرُوا لِيَسْتَيْقِنَ الَّذِينَ أُوتُوا الْكِتَابَ وَيَزْدَادَ الَّذِينَ آمَنُوا إِيمَاناً وَلَا يَرْتَابَ الَّذِينَ أُوتُوا الْكِتَابَ وَالْمُؤْمِنُونَ وَلِيَقُولَ الَّذِينَ فِي قُلُوبِهِم مَّرَضٌ وَالْكَافِرُونَ مَاذَا أَرَادَ اللَّهُ بِهَذَا مَثَلاً كَذَلِكَ يُضِلُّ اللَّهُ مَن يَشَاءُ وَيَهْدِي مَن يَشَاءُ وَمَا يَعْلَمُ جُنُودَ رَبِّكَ إِلَّا هُوَ وَمَا هِيَ إِلَّا ذِكْرَى لِلْبَشَرِ

We have appointed only angels to be wardens of the fire, and their number have We made to be a stumbling block for those who disbelieve; that those to whom the scripture hath been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture hath been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What meaneth Allah by this similitude? Thus Allah sendeth astray whom He will, and whom He will He guideth. None knoweth the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals.
