Narrated Ka'b ibn Malik: I said: Messenger of Allah, to make my repentance complete I should divest myself of my property as sadaqah (alms) for Allah and His Apostle. The Messenger of Allah (ﷺ) said: Retain some of your property, for that will be better for you. So he said: I shall retain the portion I have at Khaybar.

حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ، وَابْنُ السَّرْحِ، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، قَالَ قَالَ ابْنُ شِهَابٍ فَأَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ كَعْبِ بْنِ مَالِكٍ، أَنَّ عَبْدَ اللَّهِ بْنَ كَعْبٍ، - وَكَانَ قَائِدَ كَعْبٍ مِنْ بَنِيهِ حِينَ عَمِيَ - عَنْ كَعْبِ بْنِ مَالِكٍ، قَالَ قُلْتُ ‏:‏ يَا رَسُولَ اللَّهِ إِنَّ مِنْ تَوْبَتِي أَنْ أَنْخَلِعَ مِنْ مَالِي صَدَقَةً إِلَى اللَّهِ وَإِلَى رَسُولِهِ ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏:‏ ‏ "‏ أَمْسِكْ عَلَيْكَ بَعْضَ مَالِكَ فَهُوَ خَيْرٌ لَكَ ‏"‏ ‏.‏ قَالَ فَقُلْتُ ‏:‏ إِنِّي أُمْسِكُ سَهْمِيَ الَّذِي بِخَيْبَرَ ‏.‏
