It was narrated from Ibn Buraidah that his father said: “A woman came to the Prophet and said: ‘O Messenger of Allah, my mother has died and she owed a fast. Should I fast on her behalf?’ He said: ‘Yes.’”
حَدَّثَنَا زُهَيْرُ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ سُفْيَانَ، عَنْ عَبْدِ اللَّهِ بْنِ عَطَاءٍ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا صَوْمٌ أَفَأَصُومُ عَنْهَا قَالَ " نَعَمْ " .
