Narrated Ubaidullah bin `Abdullah bin `Utba:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، حَدَّثَنَا اللَّيْثُ ، قَالَ حَدَّثَنِي عُقَيْلٌ ، عَنِ ابْنِ شِهَابٍ ، قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ ، أَنَّ ابْنَ عَبَّاسٍ ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم غَزَا غَزْوَةَ الْفَتْحِ فِي رَمَضَانَ. قَالَ وَسَمِعْتُ ابْنَ الْمُسَيَّبِ يَقُولُ مِثْلَ ذَلِكَ. وَعَنْ عُبَيْدِ اللَّهِ أَنَّ ابْنَ عَبَّاسِ ـ رضى الله عنهما ـ قَالَ صَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم حَتَّى إِذَا بَلَغَ الْكَدِيدَ ـ الْمَاءَ الَّذِي بَيْنَ قُدَيْدٍ وَعُسْفَانَ ـ أَفْطَرَ، فَلَمْ يَزَلْ مُفْطِرًا حَتَّى انْسَلَخَ الشَّهْرُ.
Ibn `Abbas said, Allah's Messenger (ﷺ) fought the Ghazwa (i.e. battles of Al-Fath during Ramadan." Narrated Az-Zuhri: Ibn Al-Musaiyab (also) said the same. Ibn `Abbas added, "The Prophet (ﷺ) fasted and when he reached Al-Kadid, a place where there is water between Kudaid and 'Usfan, he broke his fast and did not fast afterwards till the whole month had passed away.
