Narrated 'Abdullah bin 'Abbas:

Al-Fadl was riding behind the Prophet and a woman from the tribe of Khath'am came up. Al-Fadl started looking at her and she looked at him. The Prophet turned Al-Fadl's face to the other side. She said, "My father has come under Allah's obligation of performing Hajj but he is a very old man and cannot sit properly on his Mount. Shall I perform Hajj on his behalf? The Prophet replied in the affirmative. That happened during Hajjat-ul-wada' of the Prophet .

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي سَلَمَةَ، حَدَّثَنَا ابْنُ شِهَابٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ جَاءَتِ امْرَأَةٌ مِنْ خَثْعَمَ، عَامَ حَجَّةِ الْوَدَاعِ، قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ فَرِيضَةَ اللَّهِ عَلَى عِبَادِهِ فِي الْحَجِّ أَدْرَكَتْ أَبِي شَيْخًا كَبِيرًا، لاَ يَسْتَطِيعُ أَنْ يَسْتَوِيَ عَلَى الرَّاحِلَةِ فَهَلْ يَقْضِي عَنْهُ أَنْ أَحُجَّ عَنْهُ قَالَ " نَعَمْ ".
