حَدَّثَنَا عَبْدُ الرَّزَّاقِ عَنْ مَعْمَرٍ قَالَ قَالَ الزُّهْرِيُّ فَأَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ فِي رَمَضَانَ مِنْ الْمَدِينَةِ مَعَهُ عَشْرَةُ آلَافٍ مِنْ الْمُسْلِمِينَ وَذَلِكَ عَلَى رَأْسِ ثَمَانِ سِنِينَ وَنِصْفٍ مِنْ مَقْدَمِهِ الْمَدِينَةَ فَسَارَ بِمَنْ مَعَهُ مِنْ الْمُسْلِمِينَ إِلَى مَكَّةَ يَصُومُ وَيَصُومُونَ حَتَّى إِذَا بَلَغَ الْكَدِيدَ وَهُوَ مَا بَيْنَ عُسْفَانَ وَقُدَيْدٍ أَفْطَرَ وَأَفْطَرَ الْمُسْلِمُونَ مَعَهُ فَلَمْ يَصُمْ
مسند امام احمد بن حنبل · Hadith 3089
It was narrated from lbn 'Abbas (RA) that the Prophet (PBUH) set out from Madinah in Ramadan with ten thousand Muslims. That was eight and a half years after he came to Madinah. He and the Muslims with him travelled towards Makkah; he was fasting and they were fasting too until, when he reached al-Kadeed, which is between "Usfan and Qudaid, he broke his fast and the Muslims with him broke their fast, then he did not fast.
