Mishkat al-Masabih 7 Fasting كتاب الصوم 53

وَعَنْ عَامِرِ بْنِ رَبِيعَةَ قَالَ: رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا لَا أُحْصِي يَتَسَوَّكُ وَهُوَ صَائِمٌ “. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ

‘Amir b. Rabi’a said he had seen the Prophet more often than he could count using a toothstick while he was fasting. Tirmidhi and Abu Dawud transmitted it.
