[Machine] The Prophet ﷺ said, "Using the siwak (toothstick) is a means of purification for the mouth and pleasing to the Lord." The Prophet is Muhammad, the son of Abdullah, the son of Abi Atiq, who is related to his grandfather. It is also said that Abdul Rahman narrated this from Qasim ibn Muhammad, as if he heard it from both of them.
النَّبِيَّ ﷺ قَالَ السِّوَاكُ مَطْهَرَةٌ لِلْفَمِ مَرْضَاةٌ لِلرَّبِّ عَبْدُ الرَّحْمَنِ هُوَ ابْنُ عَبْدِ اللهِ بْنِ أَبِي عَتِيقٍ نِسْبَةً إِلَى جَدِّهِ وَقِيلَ عَبْدُ الرَّحْمَنِ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ فَكَأَنَّهُ سَمِعَهُ مِنْهُمَا جَمِيعًا
