Ahmed bin al-Miqdam narrates from Fdyl bin Sulaiman al-Nmyry narrating from Abu Hazim narrating from Sahl bin Sad bin Malik.
Narrated Sahl bin Sa`d: I saw Allah's Apostle pointing with his index and middle fingers, saying. "The time of my Advent and the Hour are like these two fingers." The Great Catastrophe will overwhelm everything.
حَدَّثَنَا أَحْمَدُ بْنُ الْمِقْدَامِ، حَدَّثَنَا الْفُضَيْلُ بْنُ سُلَيْمَانَ، حَدَّثَنَا أَبُو حَازِمٍ، حَدَّثَنَا سَهْلُ بْنُ سَعْدٍ ـ رضى الله عنه ـ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ بِإِصْبَعَيْهِ هَكَذَا بِالْوُسْطَى وَالَّتِي تَلِي الإِبْهَامَ " بُعِثْتُ وَالسَّاعَةَ كَهَاتَيْنِ ".
