حَدَّثَنَا عَلِيُّ بْنُ عَيَّاشٍ، قَالَ: حَدَّثَنَا حَسَّانُ بْنُ نُوحٍ حِمْصِيٌّ، قَالَ: رَأَيْتُ عَبْدَ اللَّهِ بْنَ بُسْرٍ، يَقُولُ: تَرَوْنَ كَفِّي هَذِهِ، فَأَشْهَدُ أَنِّي وَضَعْتُهَا عَلَى كَفِّ مُحَمَّدٍ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ وَنَهَى عَنْ صِيَامِ يَوْمِ السَّبْتِ، إِلَّا فِي فَرِيضَةٍ، وَقَالَ: «إِنْ لَمْ يَجِدْ أَحَدُكُمْ إِلَّا لِحَاءَ شَجَرَةٍ فَلْيُفْطِرْ عَلَيْهِ
Ḥassān ibn Nūḥ al-Ḥimṣī reported: I saw ʿAbdullāh ibn Busr (may Allah be pleased with him) saying, “Do you see this palm of mine? I bear witness that I placed it on the palm of Muḥammad ﷺ.” He forbade fasting on Saturday except as an obligatory fast, and said, “If one of you finds nothing but the bark of a tree, let him break his fast with it.” Reference: Musnad Aḥmad 306
