Sahih Muslim , Book 41, Hadith 7025 (USC-MSA) ⓘ
`Abdullah b. `Amr reported: I committed to memory a hadith from Allah's Messenger and I did not forget it after I had heard Allah's Messenger as saying: The first sign (out of the signs of the appearance of the Dajjal) would be the appearance of the sun from the west, the appearance of the beast before the people in the forenoon and which of the two happens first, the second one would follow immediately after that.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، عَنْ أَبِي حَيَّانَ، عَنْ أَبِي زُرْعَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ حَفِظْتُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم حَدِيثًا لَمْ أَنْسَهُ بَعْدُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِنَّ أَوَّلَ الآيَاتِ خُرُوجًا طُلُوعُ الشَّمْسِ مِنْ مَغْرِبِهَا وَخُرُوجُ الدَّابَّةِ عَلَى النَّاسِ ضُحًى وَأَيُّهُمَا مَا كَانَتْ قَبْلَ صَاحِبَتِهَا فَالأُخْرَى عَلَى إِثْرِهَا قَرِيبًا " .
