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. (Using translation from Abū Dāʾūd 3317)
قُلْتُ يَا رَسُولَ اللهِ إِنَّ اللهَ إِنَّمَا نَجَّانِي بِالصِّدْقِ وَإِنَّ مِنْ تَوْبَتِي أَنْ لَا أُحَدِّثُ إِلَّا صِدْقًا مَا بَقِيتُ إِنْ شَاءَ اللهُ وَإِنَّ مِنْ تَوْبَتِي أَنْ أَنْخَلِعَ مِنْ مَالِي صَدَقَةً إِلَى اللهِ وَإِلَى رَسُولِهِ قَالَ «أَمْسِكْ عَلَيْكَ بَعْضَ مَالِكَ فَهُوَ خَيْرٌ لَكَ» قُلْتُ فَإِنِّي أَمْسِكُ سَهْمِيَ الَّذِي بِخَيْبَرَ
