[Machine] The Messenger of Allah, ﷺ , said: "The reward for the fingers is like the reward for the Siwak (tooth-stick). This is what I found in the book of 'Isa bin Shu'ayb and it is a preserved narration from Ibn Al-Muthanna."
قَالَ رَسُولُ اللهِ ﷺ تَجْزِي الْأَصَابِعُ مَجْزَى السِّوَاكِ كَذَا وَجَدْتُهُ فِي كِتَابِ عِيسَى بْنِ شُعَيْبٍ وَالْمَحْفُوظُ مِنْ حَدِيثِ ابْنِ الْمُثَنَّى
