5-52 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Ahmad ibn Muhammad ibn Isa, on the authority of Al-Hassan ibn Mahboob, on the authority of Am’mar ibn Marvan, “I heard Aba Abdullah as-Sadiq (MGB) say, ‘There is one-fifth levy on what is extracted from mines and the sea; on booties; on what is illegally obtained and is mixed with what is legally earned and no one knows its owner; and on treasures.”
IsnādMon père nous a informés, qu'Allah soit satisfait de lui, a dit: Nous a informés Muhammad ibn Yahya al-Atar, a dit: Nous a informés Ahmad ibn Muhammad ibn Isa, de al-Hasan ibn Mahbub, de Ammar ibn Marwan, a dit: J'ai entendu Abu Abdullah, que la paix soit sur lui, dire:
Dans ce qui provient des minerais, des mers, des butins, des biens licites mêlés à l'illicite lorsque le propriétaire est inconnu, des trésors, de la zakat.
