Narrated 'Abdullah bin 'Abbas:

Al-Fadl bin 'Abbas rode behind the Prophet as his companion rider on the back portion of his she camel on the Day of Nahr (slaughtering of sacrifice, 10th Dhul-Hijja) and Al-Fadl was a handsome man. The Prophet stopped to give the people verdicts. In the meantime, a beautiful woman From the tribe of Khath'am came, asking the verdict of Allah's Apostle. Al-Fadl started looking at her as her beauty attracted him. The Prophet looked behind while Al-Fadl was looking at her;
so the Prophet held out his hand backwards and caught the chin of Al-Fadl and turned his face (to the owner sides in order that he should not gaze at her. She said, "O Allah's Apostle! The obligation of Performing Hajj enjoined by Allah on His worshipers, has become due (compulsory) on my father who is an old man and who cannot sit firmly on the riding animal. Will it be sufficient that I perform Hajj on his behalf?" He said, "Yes."

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سُلَيْمَانُ بْنُ يَسَارٍ، أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ أَرْدَفَ رَسُولُ اللَّهِ ﷺ الْفَضْلَ بْنَ عَبَّاسٍ يَوْمَ النَّحْرِ خَلْفَهُ عَلَى عَجُزِ رَاحِلَتِهِ، وَكَانَ الْفَضْلُ رَجُلاً وَضِيئًا، فَوَقَفَ النَّبِيُّ ﷺ لِلنَّاسِ يُفْتِيهِمْ، وَأَقْبَلَتِ امْرَأَةٌ مِنْ خَثْعَمَ وَضِيئَةٌ تَسْتَفْتِي رَسُولَ اللَّهِ ﷺ فَطَفِقَ الْفَضْلُ يَنْظُرُ إِلَيْهَا، وَأَعْجَبَهُ حُسْنُهَا، فَالْتَفَتَ النَّبِيُّ ﷺ يَنْظُرُ إِلَيْهَا، فَأَخْلَفَ بِيَدِهِ فَأَخَذَ بِذَقَنِ الْفَضْلِ، فَعَدَلَ وَجْهَهُ عَنِ النَّظَرِ إِلَيْهَا، فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ فَرِيضَةَ اللَّهِ فِي الْحَجِّ عَلَى عِبَادِهِ أَدْرَكَتْ أَبِي شَيْخًا كَبِيرًا، لاَ يَسْتَطِيعُ أَنْ يَسْتَوِيَ عَلَى الرَّاحِلَةِ، فَهَلْ يَقْضِي عَنْهُ أَنْ أَحُجَّ عَنْهُ قَالَ " نَعَمْ ".
