Abu Zur'a reported that three persons amongst Muslims had been sitting in Medina in the presence of Marwan b. Hakam and they heard him narrate these signs from him and the first amongst them was the appearance of the Dajjal. 'Abdullah b. 'Amr reported that Marwin said nothing (particular in this connection). I, however, heard a hadith from Messenger of Allah ﷺ and I did not forget that after I had heard that from Allah's Apostle ﷺ and he reported a hadith like the foregoing.
عَبْدُ اللَّهِ بْنُ عَمْرٍو لَمْ يَقُلْ مَرْوَانُ شَيْئًا قَدْ حَفِظْتُ مِنْ رَسُولِ اللَّهِ ﷺ حَدِيثًا لَمْ أَنْسَهُ بَعْدُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ فَذَكَرَ بِمِثْلِهِ
