Nadzar puasa dan belum sempat ditunaikan maka digantikan oleh ahli waris
Imam Muslim : 1938و حَدَّثَنَا إِسْحَقُ بْنُ مَنْصُورٍ وَابْنُ أَبِي خَلَفٍ وَعَبْدُ بْنُ حُمَيْدٍ جَمِيعًا عَنْ زَكَرِيَّاءَ بْنِ عَدِيٍّ قَالَ عَبْدٌ حَدَّثَنِي زَكَرِيَّاءُ بْنُ عَدِيٍّ أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ عَمْرٍو عَنْ زَيْدِ بْنِ أَبِي أُنَيْسَةَ حَدَّثَنَا الْحَكَمُ بْنُ عُتَيْبَةَ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنْ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ جَاءَتْ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا صَوْمُ نَذْرٍ أَفَأَصُومُ عَنْهَا قَالَ أَرَأَيْتِ لَوْ كَانَ عَلَى أُمِّكِ دَيْنٌ فَقَضَيْتِيهِ أَكَانَ يُؤَدِّي ذَلِكِ عَنْهَا قَالَتْ نَعَمْ قَالَ فَصُومِي عَنْ أُمِّكِ
Narrated to us by Ishaq bin Manshur and Ibn Abu Khalaf and Abdu bin Humaid, all from Zakariya bin Adi - Abdu said - narrated to me by Zakariya bin Adi, informed us by Ubaidullah bin Amru from Zaid bin Abu Unaisah, narrated to us by Al-Hakam bin Utaibah from Sa'id bin Jubair from Ibn Abbas, may Allah be pleased with both of them, he said A woman came to the Messenger of Allah, peace and blessings be upon him, and said, 'O Messenger of Allah, indeed my mother has died, while she still has a debt of vowed fasting, may I pay it?' He replied: 'What do you think, if your mother had a debt, and you paid it, would that pay off her debt?' The woman replied, 'Yes.' He said: 'If so, fast for her.'
