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)
عَنْ رَسُولِ اللهِ ﷺ فِي غَزْوَةِ تَبُوكَ قَالَ قُلْتُ يَا رَسُولَ اللهِ إِنَّ مِنْ تَوْبَتِي أَنْ أَنْخَلِعَ مِنْ مَالِي صَدَقَةً إِلَى اللهِ وَإِلَى رَسُولِهِ قَالَ رَسُولُ اللهِ ﷺ «أَمْسِكْ عَلَيْكَ بَعْضَ مَالِكَ فَهُوَ خَيْرٌ لَكَ» قُلْتُ فَإِنِّي أَمْسِكُ سَهْمِي الَّذِي بِخَيْبَرَ
