عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ صَامَ فِي سَفَرٍ عَامَ الْفَتْحِ وَأَمَرَ أَصْحَابَهُ بِالْإِفْطَارِ، وَقَالَ: ((إِنَّكُمْ تَلْقَوْنَ عَدُوَّكُمْ فَتَقَوَّوْا))، فَقِيلَ: يَا رَسُولَ اللَّهِ! إِنَّ النَّاسَ قَدْ صَامُوا لِصِيَامِكَ فَلَمَّا أَتَى الْكَدِيدَ أَفْطَرَ، قَالَ الَّذِي حَدَّثَنِي فَلَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَصُبُّ الْمَاءَ عَلَى رَأْسِهِ مِنَ الْحَرِّ وَهُوَ صَائِمٌ
It is narrated from a Companion (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) kept a fast during the journey in the year of the conquest of Makkah, but he ordered the Companions not to fast and said: "You are going to face the enemy, therefore (by leaving the fast) gain strength." Someone said: "O Messenger of Allah! People are also fasting based on your fasting." So when the Prophet (peace and blessings be upon him and his family) reached the place of Kadid, he broke his fast. The one who narrated to me also said: "I saw that the Prophet (peace and blessings be upon him and his family) used to pour water over his head because of the heat, while he was in the state of fasting."
