[Machine] Abu al-Dhahak ibn Abi Asim Al-Nabeel narrated to me that Muhammad ibn Musa narrated to us, that Isa ibn Shuayb narrated to us, that Ibn al-Muthanna narrated it from Al-Nadr ibn Anas, from his father, who said: The Messenger of Allah ﷺ said, "Using the Siwak rewards for every finger." This narration was specifically mentioned by Uqbah ibn Mukram from Isa ibn Shuayb, and he is the only one who transmitted it through both chains of narration.
حَدَّثَنِي أَبُو الضَّحَّاكِ بْنُ أَبِي عَاصِمٍ النَّبِيلُ ثنا مُحَمَّدُ بْنُ مُوسَى ثنا عِيسَى بْنُ شُعَيْبٍ ثنا ابْنُ الْمُثَنَّى عَنِ النَّضْرِ بْنِ أَنَسٍ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللهِ ﷺ تَجْزِي مِنَ السِّوَاكِ الْأَصَابِعُ تَابَعَهُمَا عُقْبَةُ بْنُ مُكْرَمٍ عَنْ عِيسَى بْنِ شُعَيْبٍ تَفَرَّدَ بِهِ عِيسَى بِالْإِسْنَادَيْنِ جَمِيعًا
