If A Person Dies With A Vow Unfulfilled
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ اسْتَفْتَى سَعْدُ بْنُ عُبَادَةَ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَتُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اقْضِهِ عَنْهَا " .
It was narrated that Ibn 'Abbas said: "Sa'd bin 'Ubadah asked the Messenger of Allah (ﷺ) about a vow which his mother had sworn, but she died before she could fulfill it. The Messenger of Allah (ﷺ) said: 'Fulfill it on her behalf.'"
