﴿ إِذَا رَأَتْهُم مِّن مَّكَانٍۭ بَعِيدٍۢ سَمِعُوا۟ لَهَا تَغَيُّظًۭا وَزَفِيرًۭا ﴾

“when it shall face them from afar, they will hear its angry roar and its hiss;”

(When it) the Fire (seeth them from afar) from a distance of 500 years, (they bear the cracking) the exasperation which is akin to that of human beings (and the roar) similar to the braying of a donkey (thereof) coming from the Fire.
