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
