Arabic (Original)
حَدَّثَنَا سُفْيَانُ حَدَّثَنَا الزُّهْرِيُّ عَنْ عُبَيْدِ اللَّهِ عَنِ ابْنِ عَبَّاسٍ أَنَّ سَعْدَ بْنَ عُبَادَةَ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ نَذْرٍ كَانَ عَلَى أُمِّهِ تُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ اقْضِهِ عَنْهَا.
English Translation
Sa'd ibn 'Ubadah asked the Prophet (peace be upon him) about a vow that was upon his mother — she had died before fulfilling it. The Prophet said: "Fulfill it on her behalf."
