وَلِمُسْلِمٍ: «أَمْسِكُوا عَلَيْكُمْ أَمْوَالَكُمْ وَلَا تُفْسِدُوهَا، فَإِنَّهُ مَنْ أَعْمَرَ عُمْرَى فَهِيَ لِلَّذِي أُعْمِرَهَا حَياً وَمَيِّتًا، وَلِعَقِبِهِ»
“Keep your properties for yourselves and do not squander them, for if anyone gives a life-tenancy it goes to the one to whom it is given, both during his life and after his death, and to his descendants.”
