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 بِالْمَدِينَةِ وَهُوَ يَتَغَدَّى فَقَالَ لَهُ النَّبِيُّ ﷺ «هَلُمَّ إِلَى الْغَدَاءِ» قَالَ إِنِّي صَائِمٌ فَقَالَ لَهُ النَّبِيُّ ﷺ «إِنَّ اللهَ وَضَعَ عَنِ الْمُسَافِرِ الصَّوْمَ وَشَطْرَ الصَّلَاةِ وَعَنِ الْحُبْلَى وَالْمُرْضِعِ»
