Inheriting effective control of a major trade entrepôt such as Basra, Muhammad became enormously wealthy.[28] At his death, his wealth, reportedly amounted to sixty million dirhams, was confiscated by Caliph Harun al-Rashid.[29] Muhammad also appears to have been a "great hoarder", who never threw anything away.[28] Al-Tabari reports that Harun's agents found a huge trove of possessions, from valuable gifts sent from the provinces he governed even to the various items of clothing he had worn during his life, down to the ink-stained clothes he had worn in Quran school.
