Humayd ibn Ziyad has narrated from Ahmad ibn Sama‘ah from those whom he has mentioned from Aban from abu Maryam who has said the foilowing: “I once asked abu ’Abd Allah (a.s.), about plantation and what is subject to Zakat from it.

He (the Imam) said, ‘There is Zakat on wheat, barley, corn, rice, al-sult, and lintels and all of these are subject to Zakat.’ He (the Imam) said, ‘Everything that is measured by al-Sa‘ and amounts to al- Awsaq are subject to Zakat.’” سكت عنه - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/24))
