Why it matters
Zakat is not just "charity" in the optional sense — it is a duty. The Quran repeatedly pairs it with prayer (Salat), showing how central it is to a believer's faith. Allah says about the believers:
> "…who establish regular Prayer, and give regular Charity, and have (in their hearts) the assurance of the Hereafter." [Coran, Sourate Luqman:4]
And He describes the believers as those "who are active in deeds of charity" [Coran, Sourate Al-Muminoon:4]. Conversely, the Quran warns that refusing to give it is a serious matter, describing those "who practise not regular Charity, and who even deny the Hereafter" [Coran, Sourate Fussilat:7].
Who receives it
Zakat is not given randomly — Allah Himself defined the eight categories of eligible recipients:
> "Alms are for the poor and the needy, and those employed to administer the (funds); for those whose hearts have been (recently) reconciled (to Truth); for those in bondage and in debt; in the cause of Allah; and for the wayfarer: (thus is it) ordained by Allah, and Allah is full of knowledge and wisdom." [Coran, Sourate At-Tawba:60]
So the poor, the needy, those in debt, the traveler in distress, and others listed above are the rightful recipients.
When it becomes obligatory (the nisab)
Zakat is only due on wealth that reaches a minimum threshold. The Prophet ﷺ explained this clearly:
> "Zakah is not due on what is less than five ounces, nor on what is less than five camels, nor on what is less than five Wasqs." [Sahih Bukhari & Muslim — authentic hadith]
In practice, this means: if you own less than the nisab, you are not required to pay Zakat — you are considered among those who may *receive* it. The nisab for money is roughly the value of 85 grams of gold (or 595 grams of silver), and Zakat is generally 2.5% of the wealth held for a full lunar year.
A related but distinct obligation: Zakat al-Fitr
Don't confuse Zakat on wealth with *Zakat al-Fitr*, a separate charity given at the end of Ramadan. The Prophet ﷺ "enjoined Zakat al-Fitr as one Sā' of dates or one Sā' of barley on the slave and the free person, the male and the female, the young and the old from among the Muslims. He ordered that it be given before the people go out to the prayer" [Sahih Bukhari & Muslim — authentic hadith]. It is a smaller, per-person amount given before the Eid prayer.
A practical tip
Zakat is a yearly obligation, so it helps to track your wealth and know your Zakat date. You can use the Zakat calculator feature in your Al Muslim Plus application to work out exactly how much you owe, and consult the app's Islamic calendar to remember your annual Zakat date. For complex cases involving business assets, property, or debts, it's always best to consult a qualified scholar.
