[Machine] Ibn Abbas, indeed there is for you in the Messenger of Allah a good example, and then he recited, "And We ransomed him with a great sacrifice."  

الطبراني:١١٤٤٣ – حَدَّثَنَا أَحْمَدُ بْنُ رِشْدِينَ ثنا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ ثنا ابْنُ وَهْبٍ حَدَّثَنِي اللَّيْثُ قَالَ قَالَ يَحْيَى بْنُ سَعِيدٍ وَزَعَمَ ابْنُ جُرَيْجٍ أَنَّ عَطَاءَ بْنَ أَبِي رَبَاحٍ حَدَّثَهُ أَنَّ رَجُلًا أَتَى ابْنَ عَبَّاسٍ فَقَالَ إِنِّي نَذَرْتُ لأذْبَحَنَّ نَفْسِي فَقَالَ

ابْنُ عَبَّاسٍ لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللهِ أُسْوَةٌ حَسَنَةٌ ثُمَّ تَلَا {وفديناهُ بِذِبْحٍ عَظِيمٍ}

If someone says to his wife, "You are unlawful to me." he must make an expiation (for his oath). Ibn ʿAbbas added: There is for you in Messenger of Allah ﷺ, an excellent example to follow.  

البخاري:٤٩١١ – حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ حَدَّثَنَا هِشَامٌ عَنْ يَحْيَى عَنِ ابْنِ حَكِيمٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ أَنَّ ابْنَ عَبَّاسٍ ؓ قَالَ فِي الْحَرَامِ يُكَفِّرُ

وَقَالَ ابْنُ عَبَّاسٍ {لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ إِسْوَةٌ حَسَنَةٌ}

Verily, there is in the Messenger of Allah ﷺ a model pattern for you.  

مسلم:١٤٧٣a – وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ عَنْ هِشَامٍ يَعْنِي الدَّسْتَوَائِيَّ قَالَ كَتَبَ إِلَىَّ يَحْيَى بْنُ أَبِي كَثِيرٍ يُحَدِّثُ عَنْ يَعْلَى بْنِ حَكِيمٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ

أَنَّهُ كَانَ يَقُولُ فِي الْحَرَامِ يَمِينٌ يُكَفِّرُهَا وَقَالَ ابْنُ عَبَّاسٍ { لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ}
