أَخْبَرَنَا عُثْمَانُ بْنُ مُحَمَّدُ ، حَدَّثَنَا يُونُسُ ، عَنْ الزُّهْرِيِّ ، عَنْ صَفْوَانَ بْنِ عَبْدِ اللَّهِ ، عَنْ أُمِّ الدَّرْدَاءِ ، عَنْ كَعْبِ بْنِ عَاصِمٍ الْأَشْعَرِيِّ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" لَيْسَ مِنْ الْبِرِّ الصِّيَامُ فِي السَّفَرِ "

Othman bin Muhammad told us, Yunus told us, on the authority of Al-Zuhri, on the authority of Safwan bin Abdullah, on the authority of Umm Al-Darda, on the authority of Ka’b bin Asim Al-Ash’ari, that the Messenger of God, may God bless him and grant him peace, said: “It is not righteous to fast while traveling.”
