We used to go to Imran b. Husain passing in front of Hisham b. 'Amir. He, one day, said: You pass by me (in order) to go to some persons, but (amongst the living persons) none remained in the company of Messenger of Allah ﷺ more than I and none knows more ahadith than I. I heard Messenger of Allah ﷺ as saying: There would be no creation (creating more trouble) than the Dajjal right from the creation of Adam to the Last Hour. (Using translation from Muslim 2946a)
هِشَامُ بْنُ عَامِرٍ لِجِيرَانِهِ إِنَّكُمْ لَتَخُطُّونَ إِلَى رِجَالٍ مَا كَانُوا بِأَحْضَرَ لِرَسُولِ اللهِ ﷺ وَلَا أَوْعَى لِحَدِيثِهِ مِنِّي وَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا بَيْنَ خَلْقِ آدَمَ إِلَى قِيَامِ السَّاعَةِ أَمْرٌ أَكْبَرُ مِنَ الدَّجَّالِ
