Arabic (Original)
حَدَّثَنَا سُفْيَانُ عَنِ الزُّهْرِيِّ عَنْ صَفْوَانَ بْنِ عَبْدِ اللَّهِ بْنِ صَفْوَانَ عَنْ أُمِّ الدَّرْدَاءِ عَنْ كَعْبِ بْنِ عَاصِمٍ الْأَشْعَرِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَيْسَ مِنْ الْبِرِّ الصِّيَامُ فِي السَّفَرِ.
English Translation
Sufyan told us, from al-Zuhri, from Safwan ibn Abdullah ibn Safwan, from Umm al-Darda, from Ka'b ibn Asim al-Ash'ari, that the Messenger of Allah (peace and blessings be upon him) said: "It is not righteousness to fast while traveling."
