Al-Muddaththir 74:31 وما جعلنا اصحاب النار الا ملايكة وما جعلنا عدتهم الا فتنة للذين كفروا ليستيقن الذين اوتوا الكتاب ويزداد الذين امنوا ايمانا ولا يرتاب الذين اوتوا الكتاب والمومنون وليقول الذين في قلوبهم مرض والكافرون ماذا اراد الله بهاذا مثلا كذالك يضل الله من يشاء ويهدي من يشاء وما يعلم جنود ربك الا هو وما هي الا ذكرى للبشر ٣١

We have appointed only ˹stern˺ angels as wardens of the Fire. And We have made their number only as a test for the disbelievers,¹ so that the People of the Book will be certain, and the believers will increase in faith, and neither the People of the Book nor the believers will have any doubts, and so that those ˹hypocrites˺ with sickness in their hearts and the disbelievers will argue, “What does Allah mean by such a number?” In this way Allah leaves whoever He wills to stray and guides whoever He wills. And none knows the forces of your Lord except He. And this ˹description of Hell˺ is only a reminder to humanity.
