Yahya related to me from Malik from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud from Abdullah ibn Abbas that Sad ibn Ubada questioned the Messenger of Allah ﷺ and said,"My mother died while she still had a vow which she had not fulfilled." The Messenger of Allah ﷺ said, "Fulfill it for her."
أَنَّ سَعْدَ بْنَ عُبَادَةَ اسْتَفْتَى رَسُولَ اللَّهِ ﷺ فَقَالَ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا نَذْرٌ وَلَمْ تَقْضِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ اقْضِهِ عَنْهَا
