Hadith 10:269
On his father’s authority he said his grandfather told of a man coming to the Prophet and saying, “I am poor with no possessions and I have an orphan to care for.” He replied, “Eat from your orphan’s property, provided you are not extravagant, or take anything before you need it, or store up any of it.” Abu Dawud, Nasa’i and Ibn Majah transmitted it.
وَعنهُ وَعَن أَبِيهِ عَنْ جَدِّهِ: أَنَّ رَجُلًا أَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: إِنِّي فَقِيرٌ لَيْسَ لِي شَيْءٌ وَلِي يَتِيمٌ فَقَالَ: «كُلْ مِنْ مَالِ يَتِيمِكَ غَيْرَ مُسْرِفٍ وَلَا مُبَادِرٍ وَلَا مُتَأَثِّلٍ» . رَوَاهُ أَبُو دَاوُدَ وَالنَّسَائِيُّ وَابْنُ مَاجَه
