﴿ وَمَا جَعَلْنَآ أَصْحَٰبَ ٱلنَّارِ إِلَّا مَلَٰٓئِكَةًۭ ۙ وَمَا جَعَلْنَا عِدَّتَهُمْ إِلَّا فِتْنَةًۭ لِّلَّذِينَ كَفَرُوا۟ لِيَسْتَيْقِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ وَيَزْدَادَ ٱلَّذِينَ ءَامَنُوٓا۟ إِيمَٰنًۭا ۙ وَلَا يَرْتَابَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ وَٱلْمُؤْمِنُونَ ۙ وَلِيَقُولَ ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ وَٱلْكَٰفِرُونَ مَاذَآ أَرَادَ ٱللَّهُ بِهَٰذَا مَثَلًۭا ۚ كَذَٰلِكَ يُضِلُّ ٱللَّهُ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۚ وَمَا يَعْلَمُ جُنُودَ رَبِّكَ إِلَّا هُوَ ۚ وَمَا هِىَ إِلَّا ذِكْرَىٰ لِلْبَشَرِ ﴾

“For We have caused none but angelic powers to lord over the fire [of hell]; and We have not caused their number to be aught but a trial for those who are bent on denying the truth - to the end that they who have been granted revelation aforetime might be convinced [of the truth of this divine writ]; and that they who have attained to faith [in it] might grow yet more firm in their faith; and that [both] they who have been granted the earlier revelation and they who believe [in this one] might be freed of all doubt; and that they in whose hearts is disease and the who deny the truth outright might ask, "What does [your] God mean by this parable?" In this way God lets go astray him that wills [to go astray], and guides aright him that wills [to be guided]. And none can comprehend thy Sustainers forces save Him alone: and all this is but a reminder to mortal man.”

And We have appointed only angels as wardens of the Fire in other words and so they cannot be withstood as these disbelievers are wont to imagine; and We have made their number so only as a stumbling-block a cause for error for those who disbelieve when they then say ‘Why are there nineteen of them?’ so that those who were given the Scripture namely the Jews may be certain of the sincerity of the Prophet s in saying that they are nineteen for this concords with what is in their Scripture; and that those who believe from among the People of the Scripture may increase in faith in affirmation of the truth given that what the Prophet s has said concords with what is in their Scripture and that those given the Scripture and the believers those other than these Jews may not be in doubt concerning the number of these angels and that those in whose hearts there is a sickness an uncertainty those in Medina and the disbelievers in Mecca may say ‘What did God mean by this number as a similitude?’ mathalan they referred to it thus as a mathal on account of it being a curious matter; in terms of syntax it mathalan is a circumstantial qualifier. Thus that is just as the one who rejects this number is led astray and the one who affirms the truth of it is guided God leads astray whom He will and guides whom He will. And none knows the hosts of your Lord namely the angels none knows them in terms of their strength and their assistants except Him. And it that is Saqar is nothing but a reminder for humans.
