Ibn Jamil is taking revenge but for this that he was destitute and Allah made him rich. As regards Khalid, you are unjust to Khalid, for be reserved his armours and weapons for the sake of Allah, and as for 'Abbas, I shall be responsible for it and an equal amount along with it. And he again said: 'Umar, bear this in mind, the uncle of a person is like his father. (Using translation from Muslim 983)
بَعَثَ رَسُولُ اللهِ ﷺ عُمَرَ عَلَى الصَّدَقَةِ فَقِيلَ مَنَعَ ابْنُ جَمِيلٍ وَخَالِدُ بْنُ الْوَلِيدِ وَالْعَبَّاسُ عَمُّ النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ مَا يَنْقِمُ ابْنُ جَمِيلٍ إِلَّا أَنَّهُ كَانَ فَقِيرًا فَأَغْنَاهُ اللهُ وَأَمَّا خَالِدٌ فَإِنَّكُمْ تَظْلِمُونَ خَالِدًا فَقَدِ احْتَبَسَ أَدْرَاعَهُ فِي سَبِيلِ اللهِ وَأَمَّا الْعَبَّاسُ فَهِيَ عَلَيَّ وَمِثْلُهَا ثُمَّ قَالَ أَمَا عَلِمْتَ أَنَّعَمَّ الرَّجُلِ صِنْوُ أَبِيهِ
