وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، أَنَّ رَجُلاً، مِنَ الأَنْصَارِ كَانَ يُصَلِّي فِي حَائِطٍ لَهُ بِالْقُفِّ - وَادٍ مِنْ أَوْدِيَةِ الْمَدِينَةِ - فِي زَمَانِ الثَّمَرِ وَالنَّخْلُ قَدْ ذُلِّلَتْ فَهِيَ مُطَوَّقَةٌ بِثَمَرِهَا فَنَظَرَ إِلَيْهَا فَأَعْجَبَهُ مَا رَأَى مِنْ ثَمَرِهَا ثُمَّ رَجَعَ إِلَى صَلاَتِهِ فَإِذَا هُوَ لاَ يَدْرِي كَمْ صَلَّى فَقَالَ لَقَدْ أَصَابَتْنِي فِي مَالِي هَذَا فِتْنَةٌ ‏.‏ فَجَاءَ عُثْمَانَ بْنَ عَفَّانَ - وَهُوَ يَوْمَئِذٍ خَلِيفَةٌ - فَذَكَرَ لَهُ ذَلِكَ وَقَالَ هُوَ صَدَقَةٌ فَاجْعَلْهُ فِي سُبُلِ الْخَيْرِ ‏.‏ فَبَاعَهُ عُثْمَانُ بْنُ عَفَّانَ بِخَمْسِينَ أَلْفًا فَسُمِّيَ ذَلِكَ الْمَالُ الْخَمْسِينَ ‏.‏
