Sunan Ibn Majah, Volume 4, Book 25, Hadith 2909 (DarusSalam) ⓘ

It was narrated from Ibn ‘Abbas that his brother Fadl was riding behind the Messenger of Allah in the morning of sacrifice (i.e., the 10th of Dhul-Hijjah), when a woman from Khath’am came and said: “O Messenger of Allah, the command of Allah has come for His slaves to perform Hajj, but my father is an old man and cannot ride. May I perform Hajj on his behalf?” He said: “Yes, because if your father owed a debt you would pay it off.”

حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، عَنِ الزُّهْرِيِّ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنِ ابْنِ عَبَّاسٍ، عَنْ أَخِيهِ الْفَضْلِ، أَنَّهُ كَانَ رِدْفَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ غَدَاةَ النَّحْرِ فَأَتَتْهُ امْرَأَةٌ مِنْ خَثْعَمٍ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ فَرِيضَةَ اللَّهِ فِي الْحَجِّ عَلَى عِبَادِهِ أَدْرَكَتْ أَبِي شَيْخًا كَبِيرًا لاَ يَسْتَطِيعُ أَنْ يَرْكَبَ أَفَأَحُجُّ عَنْهُ قَالَ ‏ "‏ نَعَمْ فَإِنَّهُ لَوْ كَانَ عَلَى أَبِيكِ دَيْنٌ قَضَيْتِيهِ ‏" ‏ ‏.‏
