3. A number of our people have narrated from Sahl ibn Ziyad and Ahmad ibn Muhammad from all from ibn Mahbub from ‘Abd Allah ibn Sinan who has said the following: “About the words of Allah, most Majestic, most Glorious, ‘He must eat to the proper limit’, abu ‘Abd Allah , has said, ‘Al-Ma‘ruf (proper limit) is what one needs for sustenance. It applies to the executor of the will or one who is appointed as the custodian of their assets and to work for their welfare.’”
