حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ الدِّمَشْقِيُّ، حَدَّثَنَا الرَّبِيعُ بْنُ بَدْرٍ، عَنِ الْجُرَيْرِيِّ، عَنِ الْحَسَنِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ رَخَّصَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ لِلْحُبْلَى الَّتِي تَخَافُ عَلَى نَفْسِهَا أَنْ تُفْطِرَ وَلِلْمُرْضِعِ الَّتِي تَخَافُ عَلَى وَلَدِهَا ‏.‏
Translation
It wasnarrated from Anas bin Malik that a man from the tribe of Banu‘Abdul-Ashhal, while (one narrator) ‘Ali bin Muhammad said (hewas) aman from the tribe of Banu ‘Abdullah bin Ka’b, said

“Thecavalry ofthe Messenger of Allah (ﷺ) attacked us, so I came to theMessengerof Allah (ﷺ) while he was eating a meal. He said: ‘Comeand eat.’ Isaid: ‘I am fasting.’ He said: ‘Sit down and Iwill tell you aboutfasting. Allah has relieved the traveler of halfof the prayer, and Hehas relieved the traveler, the pregnant, andthe nursing mothers ofthe duty to fast.’ By Allah, the Prophet(ﷺ) said them, both, or oneof them, and now I feel so disappointedthat I had not eaten of thefood of the Messenger of Allah (ﷺ).”
