ذِكْرُ الْأَمْرِ بِقَضَاءِ نَذَرِ النَّاذِرِ إِذَا مَاتَ قَبْلَ أَنْ يَفِيَ بِنَذْرِهِ
Sa'd b. 'Ubadah asked the Messenger of Allah ﷺ: My Mother has died and she could not fulfill her vow which she had taken. The Messenger of Allah ﷺ said: Fulfill it on her behalf. (Using translation from Abū Dāʾūd 3307)
أَنَّ سَعْدَ بْنَ عُبَادَةَ اسْتَفْتَى رَسُولَ اللَّهِ ﷺ فَقَالَ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا نَذَرٌ لَمْ تَقْضِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «اقْضِهِ عَنْهَا»
