It was narrated from Anas bin Malik that a man from the tribe of Banu ‘Abdul-Ashhal, while (one narrator) ‘Ali bin Muhammad said (he was) a man from the tribe of Banu ‘Abdullah bin Ka’b, said:
“The cavalry of the Messenger of Allah ﷺ attacked us, so I came to the Messenger of Allah ﷺ while he was eating a meal. He said: ‘Come and eat.’ I said: ‘I am fasting.’ He said: ‘Sit down and I will tell you about fasting. Allah has relieved the traveler of half of the prayer, and He has relieved the traveler, the pregnant, and the nursing mothers of the duty to fast.’ By Allah, the Prophet ﷺ said them, both, or one of them, and now I feel so disappointed that I had not eaten of the food of the Messenger of Allah ﷺ.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، عَنْ أَبِي هِلاَلٍ، عَنْ عَبْدِ اللَّهِ بْنِ سَوَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، - رَجُلٌ مِنْ بَنِي عَبْدِ الأَشْهَلِ وَقَالَ عَلِيُّ بْنُ مُحَمَّدٍ مِنْ بَنِي عَبْدِ اللَّهِ بْنِ كَعْبٍ - قَالَ أَغَارَتْ عَلَيْنَا خَيْلُ رَسُولِ اللَّهِ ـ ﷺ ـ فَأَتَيْتُ رَسُولَ اللَّهِ ـ ﷺ ـ وَهُوَ يَتَغَدَّى فَقَالَ " ادْنُ فَكُلْ " . قُلْتُ إِنِّي صَائِمٌ . قَالَ " اجْلِسْ أُحَدِّثْكَ عَنِ الصَّوْمِ أَوِ الصِّيَامِ . إِنَّ اللَّهَ عَزَّ وَجَلَّ وَضَعَ عَنِ الْمُسَافِرِ شَطْرَ الصَّلاَةِ وَعَنِ الْمُسَافِرِ وَالْحَامِلِ وَالْمُرْضِعِ الصَّوْمَ أَوِ الصِّيَامَ " . وَاللَّهِ لَقَدْ قَالَهُمَا النَّبِيُّ ـ ﷺ ـ كِلْتَاهُمَا أَوْ إِحْدَاهُمَا فَيَا لَهْفَ نَفْسِي فَهَلاَّ كُنْتُ طَعِمْتُ مِنْ طَعَامِ رَسُولِ اللَّهِ ـ ﷺ ـ .
