Muwatta Imam Malik Book of Fasting, Hadith 22

Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman, from Abu Bakr ibn Abd ar-Rahman from one of the companions of the Messenger of Allah, that the Messenger of Allah ﷺ ordered everyone to break the fast on the journey he made in the year of the conquest saying, "Be strong for your enemy," while the Messenger of Allah ﷺ kept on fasting. Abu Bakr said that the one who related this to him said, "I saw the Messenger of Allah ﷺ pouring water over his head at al-Arj, either from thirst or from the heat. Then some one said to the Messenger of Allah ﷺ 'Messenger of Allah, a group of people kept on fasting when you did.' Then when the Messenger of Allah was at al-Kadid, he asked for a drinking-bowl and drank, and everyone broke the fast."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ بَعْضِ، أَصْحَابِ رَسُولِ اللَّهِ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ أَمَرَ النَّاسَ فِي سَفَرِهِ عَامَ الْفَتْحِ بِالْفِطْرِ وَقَالَ " تَقَوَّوْا لِعَدُوِّكُمْ " . وَصَامَ رَسُولُ اللَّهِ ﷺ . قَالَ أَبُو بَكْرٍ قَالَ الَّذِي حَدَّثَنِي لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ بِالْعَرْجِ يَصُبُّ الْمَاءَ عَلَى رَأْسِهِ مِنَ الْعَطَشِ أَوْ مِنَ الْحَرِّ ثُمَّ قِيلَ لِرَسُولِ اللَّهِ ﷺ يَا رَسُولَ اللَّهِ إِنَّ طَائِفَةً مِنَ النَّاسِ قَدْ صَامُوا حِينَ صُمْتَ - قَالَ - فَلَمَّا كَانَ رَسُولُ اللَّهِ ﷺ بِالْكَدِيدِ دَعَا بِقَدَحٍ فَشَرِبَ فَأَفْطَرَ النَّاسُ .
