[Machine] "And Ibn Umar instructed a woman who had made her mother pray upon herself at Quba', so he said, 'Pray for her.' And Ibn Abbas said something similar to it."
وَأَمَرَ ابْنُ عُمَرَ امْرَأَةً جَعَلَتْ أُمُّهَا عَلَى نَفْسِهَا صَلاَةً بِقُبَاءٍ فَقَالَ صَلِّي عَنْهَا. وَقَالَ ابْنُ عَبَّاسٍ نَحْوَهُ.
that he consulted the Prophet ﷺ about a vow that had been made by his mother who died without fulfilling it. The Prophet ﷺ gave his verdict that he should fulfill it on her behalf. The verdict became Sunna (i.e. the Prophet's tradition).
أَخْبَرَهُ أَنَّ سَعْدَ بْنَ عُبَادَةَ الأَنْصَارِيَّ اسْتَفْتَى النَّبِيَّ ﷺ فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَتُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَأَفْتَاهُ أَنْ يَقْضِيَهُ عَنْهَا فَكَانَتْ سُنَّةً بَعْدُ
A man came to the Prophet ﷺ and said to him, "My sister vowed to perform the Hajj, but she died (before fulfilling it)." The Prophet ﷺ said, "Would you not have paid her debts if she had any?" The man said, "Yes." The Prophet ﷺ said, "So pay Allah's Rights, as He is more entitled to receive His rights."
أَتَى رَجُلٌ النَّبِيَّ ﷺ فَقَالَ لَهُ إِنَّ أُخْتِي نَذَرَتْ أَنْ تَحُجَّ وَإِنَّهَا مَاتَتْ فَقَالَ النَّبِيُّ ﷺ لَوْ كَانَ عَلَيْهَا دَيْنٌ أَكُنْتَ قَاضِيَهُ قَالَ نَعَمْ قَالَ فَاقْضِ اللَّهَ فَهْوَ أَحَقُّ بِالْقَضَاءِ
