What is the amount of savings upon which a year has passed, and how is its Zakat to be paid?

The matter of Zakat must be given attention, for it is a great pillar [of Islam]. It is obligatory to know when wealth reaches the nisab, which is equivalent to 85 grams of pure gold. Then, Zakat is paid on the wealth when a full Hijri year (hawl) has passed. If you are unaware of the amount of wealth on which a year has passed, then it is obligatory to investigate and pay Zakat with what achieves certainty or a strong presumption of fulfilling the obligation. As for the money saved from salary during the year after the nisab is reached, the majority of scholars hold that each installment must be zakated when its own year passes. However, the madhhab of Abu Hanifa obliges paying Zakat on all wealth when the year passes on the nisab, and this is easier and permissible, as it is considered an acceleration of Zakat.
