Anas reported Allah’s Messenger (ﷺ) as saying:
I and the Hour have been sent like this and (he while doing it) joined the forefinger with the middle finger.
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 .
