وَحَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، حَدَّثَنَا خَالِدٌ، - يَعْنِي ابْنَ الْحَارِثِ - حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، وَأَبَا التَّيَّاحِ، يُحَدِّثَانِ أَنَّهُمَا سَمِعَا أَنَسًا، يُحَدِّثُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " بُعِثْتُ أَنَا وَالسَّاعَةُ هَكَذَا " . وَقَرَنَ شُعْبَةُ بَيْنَ إِصْبَعَيْهِ الْمُسَبِّحَةِ وَالْوُسْطَى يَحْكِيهِ .Shu'ba reported:I heard Qatada and Abu Tayyab narrating that both of them heard Anas as narrating that Allah's Messenger (ﷺ) said: I and the Last Hour have been sent like this, and Shu'ba drew his forefinger and middle finger near each other while narrating it
