The Prophet ﷺ Said: The children of a man come from what he earns, rather they are his pleasantest earning; so enjoy from their property. Abu Dawud said: Hammad b. Abi Sulaiman added in his version: "When you need." But this (addition) is munkar (not authoritative).
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ وَلَدُ الرَّجُلِ مِنْ كَسْبِهِ مِنْ أَطْيَبِ كَسْبِهِ فَكُلُوا مِنْ أَمْوَالِهِمْ
