AHMAD 15770:
from ʿAbd al-Raḥman b. ʿAbdullāh b. Kaʿb b. Mālik —
[Machine] "When Ka'b ibn Malik repented to Allah, he went to the Messenger of Allah ﷺ and said, 'Verily, Allah has only saved me through truthfulness, and part of my repentance to Allah is that I will never lie again. And I will give a portion of my wealth as charity to Allah and His Messenger.' The Messenger of Allah ﷺ told him, 'Keep some of your wealth, as it is better for you.' He replied, 'But I will keep my bow from Khaybar.'"

عن عبد الرحمن بن عبد الله بن كعب بن مالك —
أَنَّ كَعْبَ بْنَ مَالِكٍ لَمَّا تَابَ اللهُ عَلَيْهِ أَتَى رَسُولَ اللهِ ﷺ فَقَالَ إِنَّ اللهَ لَمْ يُنْجِنِي إِلَّا بِالصِّدْقِ وَإِنَّ مِنْ تَوْبَتِي إِلَى اللهِ أَنْ لَا أَكْذِبَ أَبَدًا وَإِنِّي أَنْخَلِعُ مِنْ مَالِي صَدَقَةً لِلَّهِ وَرَسُولِهِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ أَمْسِكْ عَلَيْكَ بَعْضَ مَالِكَ فَإِنَّهُ خَيْرٌ لَكَ قَالَ فَإِنِّي أُمْسِكُ سَهْمِي مِنْ خَيْبَرَ
