Sahih Muslim · Book 54: The Book of Tribulations and Portents of the Last Hour · The Approach Of The Hour
Anas reported Allah's Messenger (ﷺ) as saying:
وَحَدَّثَنَا أَبُو غَسَّانَ الْمِسْمَعِيُّ ، حَدَّثَنَا مُعْتَمِرٌ ، عَنْ أَبِيهِ ، عَنْ مَعْبَدٍ ، عَنْ أَنَسٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بُعِثْتُ أَنَا وَالسَّاعَةُ كَهَاتَيْنِ " . قَالَ وَضَمَّ السَّبَّابَةَ وَالْوُسْطَى .
I and the Last Hour have been sent like this and (he while doing it) joined the forefinger with the middle finger.
