وَإِذَا وَقَعَ الْقَوْلُ عَلَيْهِمْ أَخْرَجْنَا لَهُمْ دَابَّةً مِنَ الْأَرْضِ تُكَلِّمُهُمْ أَنَّ النَّاسَ كَانُوا بِآيَاتِنَا لَا يُوقِنُونَ
When the decree falls upon them, We shall bring out for them a beast from the earth that will speak to them, because people had not been certain of Our signs. (al-Naml 27:82)
The Beast of the Earth is a great sign that will emerge from the ground. Its appearance belongs to the later events surrounding the Hour, and the verse explicitly mentions its speech to people.
