Sunan Abi Dawud 2423

Arabic

حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبٍ، حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ سَمِعْتُ اللَّيْثَ، يُحَدِّثُ عَنِ ابْنِ شِهَابٍ، أَنَّهُ كَانَ إِذَا ذُكِرَ لَهُ أَنَّهُ نُهِيَ عَنْ صِيَامِ يَوْمِ السَّبْتِ يَقُولُ ابْنُ شِهَابٍ هَذَا حَدِيثٌ حِمْصِيٌّ ‏.‏

Translation

Narrated Al-Laith:When it was mentioned to Ibn Shihab (al-Zuhri) that fasting on Saturday had been prohibited, he would say: This is a Himsi tradition
