Jami at-Tirmidhi · Book 33: Chapters On Al-Fitan · What Has Been Related About The Prophet's(s.a.w) Saying: "The Hour And I Have Been Dispatched Like These Two" Meaning The Index And Middle Fingers
Anas narrated that the Messenger of Allah(s.a.w) said:
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ ، حَدَّثَنَا أَبُو دَاوُدَ ، أَنْبَأَنَا شُعْبَةُ ، عَنْ قَتَادَةَ ، عَنْ أَنَسٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بُعِثْتُ أَنَا وَالسَّاعَةَ كَهَاتَيْنِ " . وَأَشَارَ أَبُو دَاوُدَ بِالسَّبَّابَةِ وَالْوُسْطَى فَمَا فَضْلُ إِحْدَاهُمَا عَلَى الأُخْرَى . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"The Hour and I were dispatched like these two" - and Abu Dawud(a narrator) indicated with his index and middle fingers- so, how much more(in length) is one then the other.
