Muslim bin Al-Hajjaj recorded that `Abdullah bin `Amr said, "I memorized a Hadith from the Messenger of Allah which I never forgot afterwards. I heard the Messenger of Allah say:

«إِنَّ أَوَّلَ الْآيَاتِ خُرُوجًا طُلُوعُ الشَّمْسِ مِنْ مَغْرِبِهَا، وَخُرُوجُ الدَّابَّةِ عَلَى النَّاسِ ضُحًى، وَأَيَّتُهُمَا مَا كَانَتْ قَبْلَ صَاحِبَتِهَا فَالْأُخْرَى عَلَى إِثْرِهَا قَرِيبًا»

(The first of the signs to appear will be the rising of the sun from the west, and the emergence of the beast to mankind in the forenoon. Whichever of them appears first, the other will follow close behind it.)
