Ibn ʿAbbas said, Messenger of Allah ﷺ fought the Ghazwa (i.e. battles of Al-Fath during Ramadan." Narrated Az-Zuhri: Ibn Al-Musaiyab (also) said the same. Ibn ʿAbbas 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.  

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ غَزَا غَزْوَةَ الْفَتْحِ فِي رَمَضَانَ قَالَ وَسَمِعْتُ ابْنَ الْمُسَيَّبِ يَقُولُ مِثْلَ ذَلِكَ وَعَنْ عُبَيْدِ اللَّهِ أَنَّ ابْنَ عَبَّاسِ ؓ قَالَ صَامَ رَسُولُ اللَّهِ ﷺ حَتَّى إِذَا بَلَغَ الْكَدِيدَ الْمَاءَ الَّذِي بَيْنَ قُدَيْدٍ وَعُسْفَانَ أَفْطَرَ فَلَمْ يَزَلْ مُفْطِرًا حَتَّى انْسَلَخَ الشَّهْرُ  

The Prophet ﷺ left Medina (for Mecca) in the company of ten-thousand (Muslim warriors) in (the month of) Ramadan, and that was eight and a half years after his migration to Medina. He and the Muslims who were with him, proceeded on their way to Mecca. He was fasting and they were fasting, but when they reached a place called Al-Kadid which was a place of water between 'Usfan and Kudaid, he broke his fast and so did they. (Az-Zuhri said, "One should take the last action of Messenger of Allah ﷺ and leave his early action (while taking a verdict.")  

أَنَّ النَّبِيَّ ﷺ خَرَجَ فِي رَمَضَانَ مِنَ الْمَدِينَةِ وَمَعَهُ عَشَرَةُ آلاَفٍ وَذَلِكَ عَلَى رَأْسِ ثَمَانِ سِنِينَ وَنِصْفٍ مِنْ مَقْدَمِهِ الْمَدِينَةَ فَسَارَ هُوَ وَمَنْ مَعَهُ مِنَ الْمُسْلِمِينَ إِلَى مَكَّةَ يَصُومُ وَيَصُومُونَ حَتَّى بَلَغَ الْكَدِيدَ وَهْوَ مَاءٌ بَيْنَ عُسْفَانَ وَقُدَيْدٍ أَفْطَرَ وَأَفْطَرُوا قَالَ الزُّهْرِيُّ وَإِنَّمَا يُؤْخَذُ مِنْ أَمْرِ رَسُولِ اللَّهِ ﷺ الآخِرُ فَالآخِرُ  

Messenger of Allah ﷺ set out towards Hunain in the month of Ramadan and some of the people were fasting while some others were not fasting, and when the Prophet ﷺ mounted his she-camel, he asked for a tumbler of milk or water and put it on the palm of his hand or on his she-camel and then the people looked at him; and those who were not fasting told those who were fasting, to break their fast (i.e. as the Prophet ﷺ had done so).  

خَرَجَ النَّبِيُّ ﷺ فِي رَمَضَانَ إِلَى حُنَيْنٍ وَالنَّاسُ مُخْتَلِفُونَ فَصَائِمٌ وَمُفْطِرٌ فَلَمَّا اسْتَوَى عَلَى رَاحِلَتِهِ دَعَا بِإِنَاءٍ مِنْ لَبَنٍ أَوْ مَاءٍ فَوَضَعَهُ عَلَى رَاحَتِهِ أَوْ عَلَى رَاحِلَتِهِ ثُمَّ نَظَرَ إِلَى النَّاسِ فَقَالَ الْمُفْطِرُونَ لِلصُّوَّامِ أَفْطِرُوا  

"The Prophet ﷺ went (to Hunain) in the year of the Conquest (of Mecca).  

عَنِ ابْنِ عَبَّاسٍ ؓ خَرَجَ النَّبِيُّ ﷺ عَامَ الْفَتْحِ وَقَالَ حَمَّادُ بْنُ زَيْدٍ عَنْ أَيُّوبَ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ عَنِ النَّبِيِّ ﷺ  

Ibn ʿAbbas said, "Messenger of Allah ﷺ travelled in the month of Ramadan and he fasted till he reached (a place called) 'Usfan, then he asked for a tumbler of water and drank it by the daytime so that the people might see him. He broke his fast till he reached Mecca." Ibn ʿAbbas used to say, "Allah's Apostle fasted and sometimes did not fast while traveling, so one may fast or may not (on journeys)"  

سَافَرَ رَسُولُ اللَّهِ ﷺ فِي رَمَضَانَ فَصَامَ حَتَّى بَلَغَ عُسْفَانَ ثُمَّ دَعَا بِإِنَاءٍ مِنْ مَاءٍ فَشَرِبَ نَهَارًا لِيُرِيَهُ النَّاسَ فَأَفْطَرَ حَتَّى قَدِمَ مَكَّةَ قَالَ وَكَانَ ابْنُ عَبَّاسٍ يَقُولُ صَامَ رَسُولُ اللَّهِ ﷺ فِي السَّفَرِ وَأَفْطَرَ فَمَنْ شَاءَ صَامَ وَمَنْ شَاءَ أَفْطَرَ
