"Tell it to us." The old man said: "My paternal uncle told me that he went to the Prophet, concerning some camels of his, while he was eating. He said: 'Come and eat.' I said: 'I am fasting.' He said: 'Allah, the mighty and sublime, has waived half of the prayer and fasting for the traveler, the pregnant woman and the sick."'  

أَنَّهُ ذَهَبَ فِي إِبِلٍ لَهُ فَانْتَهَى إِلَى النَّبِيِّ ﷺ وَهُوَ يَأْكُلُ أَوْ قَالَ يَطْعَمُ فَقَالَ ادْنُ فَكُلْ أَوْ قَالَ ادْنُ فَاطْعَمْ فَقُلْتُ إِنِّي صَائِمٌ فَقَالَ إِنَّ اللَّهَ ﷻ وَضَعَ عَنِ الْمُسَافِرِ شَطْرَ الصَّلاَةِ وَالصِّيَامَ وَعَنِ الْحَامِلِ وَالْمُرْضِعِ  

"we had been travelijng for as long as Allah willed, then we came to the Messenger of Allah and he was eating. He said: 'Come and eat.' I said: 'I am fasting.' The Messenger of Allah said: 'I will tell you about fasting. Allah has waived fasting and half of the prayer for the traveler."'  

كُنَّا نُسَافِرُ مَا شَاءَ اللَّهُ فَأَتَيْنَا رَسُولَ اللَّهِ ﷺ وَهُوَ يَطْعَمُ فَقَالَ هَلُمَّ فَاطْعَمْ فَقُلْتُ إِنِّي صَائِمٌ فَقَالَ رَسُولُ اللَّهِ ﷺ أُحَدِّثُكُمْ عَنِ الصِّيَامِ إِنَّ اللَّهَ وَضَعَ عَنِ الْمُسَافِرِ الصَّوْمَ وَشَطْرَ الصَّلاَةِ  

he came to Prophet in Al-Madinah when he was eating breakfast. The Prophet said to him: "Come and eat the breakfast." He said: "I am fasting." The Prophet said to him: "Allah, the mighty and sublime, has waived fasting and half of the prayer for the traveler and for pregnant and breastfeeding women." (Using translation from Nasāʾī 2315)   

أَنَّهُ أَتَى النَّبِيَّ ﷺ الْمَدِينَةَ وَالنَّبِيُّ ﷺ يَتَغَدَّى قَالَ فَقَالَ النَّبِيُّ ﷺ هَلُمَّ لِلْغَدَاءِ فَقُلْتُ يَا نَبِيَّ اللهِ إِنِّي صَائِمٌ فَقَالَ النَّبِيُّ ﷺ إِنَّ اللهَ وَضَعَ عَنِ الْمُسَافِرِ الصَّوْمَ وَشَطْرَ الصَّلَاةِ وَعَنِ الْحُبْلَى وَالْمُرْضِعِ
