[Machine] Sa'd ibn 'Ubadah al-Ansari sought the advice of the Messenger of Allah ﷺ regarding a vow that his mother had made but passed away before fulfilling it. The Messenger of Allah ﷺ told him, "Fulfill it on her behalf." Therefore, Muslims should consult in every matter that a person has made a commitment to, but passed away before fulfilling it.
أَنَّ سَعْدَ بْنَ عُبَادَةَ الْأَنْصَارِيَّ اسْتَفْتَى رَسُولَ اللهِ ﷺ فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَتُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «اقْضِهِ عَنْهَا» فَلْيَسْتَنَّ الْمُسْلِمُونَ فِي كُلِّ شَيْءٍ كَانَ عَلَى امْرِئٍ فَتُوُفِّيَ قَبْلَ أَنْ يَقْضِيَهُ
