Unlike prayers, we observe that even the ratio, the exemption, the kinds of wealth that are zakatable are subject to differences among scholars. Such differences have serious implications for Muslims at large when it comes to their application of the Islamic obligation of zakat. For example, some scholars consider the wealth of children and insane individuals zakatable, others don't. Some scholars consider all agricultural products zakatable, others restrict zakat to specific kinds only. Some consider debts zakatable, others don't. Similar differences exist for business assets and women's jewelry. Some require certain minimum (nisab) for zakatability, some don't. etc. The same kind of differences also exist about the disbursement of zakat.<br> – Shiekh Mahmud Shaltut
