Welcome to our Blog! In this article, we will show evidence on the permissibility of brushing teeth while fasting as most in the subcontinent consider it to be taboo.
1) Hafidh Ibn Hajr al-Asqalani mentioned :
ﻭﻗﺎﻝ ﺃﺣﻤﺪ ﺑﻦ ﻣﻨﻴﻊ ﺣﺪﺛﻨﺎ اﻟﻬﻴﺜﻢ ﺑﻦ ﺧﺎﺭﺟﺔ ﺛﻨﺎ ﻳﺤﻴﻰ ﺑﻦ ﺣﻤﺰﺓ ﻋﻦ اﻟﻨﻌﻤﺎﻥ ﺑﻦ اﻟﻤﻨﺬﺭ ﻋﻦ ﻋﻄﺎء ﻭﻃﺎﻭﻭﺱ ﻭﻣﺠﺎﻫﺪ ﻋﻦ اﺑﻦ ﻋﺒﺎﺱ ﺃﻥ اﻟﻨﺒﻲ ﷺ ﺗﺴﻮﻙ ﻭﻫﻮ ﺻﺎﺋﻢ
It is narrated in Musnad Ahmad Ibn Manea’ from Aata’, Tawoos and Mujahid that Ibn Abbas narrated :
“The Prophet ﷺ would use siwak (brush) during fast.”
~al-Matalib al-Aaliya bi-Zawaid al-Masaneed al-Thamaniya 1066

• The Muhaqqiq of the book Sa’ad Ibn Nasir al-Shithri said ‘The Sanad is Hasan‘
• Hafidh al-Busairi said all it’s narrators are Thiqah.
2) Allamah at-Tirmidhi mentioned :
عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، عَنْ أَبِيهِ، قَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم مَا لاَ أُحْصِي يَتَسَوَّكُ وَهُوَ صَائِمٌ..قَالَ أَبُو عِيسَى حَدِيثُ عَامِرِ بْنِ رَبِيعَةَ حَدِيثٌ حَسَنٌ . وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ لاَ يَرَوْنَ بِالسِّوَاكِ لِلصَّائِمِ بَأْسًا إِلاَّ أَنَّ بَعْضَ أَهْلِ الْعِلْمِ كَرِهُوا السِّوَاكَ لِلصَّائِمِ بِالْعُودِ الرَّطْبِ وَكَرِهُوا لَهُ السِّوَاكَ آخِرَ النَّهَارِ وَلَمْ يَرَ الشَّافِعِيُّ بِالسِّوَاكِ بَأْسًا أَوَّلَ النَّهَارِ وَلاَ آخِرَهُ
Aamir Ibn Rabiyyah said : ‘I saw the Prophet ﷺ frequently brushing while he was fasting.’
Abu Eesa at-Tirmidhi said: ‘The Hadith of Aamir Ibn Rabiyyah is Hasan, and this is the Amal of the people of knowledge. They would not see a problem in brushing while fasting except a few who found it makhrooh to brush with a wet brush, and some found it makhrooh to brush at the end of the fast. And ash-Shafi’i would find no problem in brushing at the start of the day or the end of the day.
~Jami’ at-Tirmidhi 725

3) Allamah al-Kulayni (May Allah elevate his name) narrated :
