What is the difference between zakāt and sadaqa?
Zakāt is obligatory, fixed in amount and timing, and restricted to eight categories of recipient. Sadaqa is voluntary, any amount, any time, to anyone — and it is not only money: a kind word, removing something harmful from a path, and even a smile are all described as sadaqa. Paying zakāt does not discharge you from sadaqa, and giving sadaqa does not substitute for zakāt.
The four schools concur on this.
The two are often used interchangeably in English, which loses a distinction that matters practically.
Zakāt is a due. It has a rate (2.5% on money), a threshold, a yearly cycle, and a fixed list of who may receive it. Not paying it when it is owed is a serious matter, and it can be calculated to the penny.
Sadaqa is a gift. There is no minimum, no maximum, no schedule, and no restriction on the recipient — you may give it to your own parents, to a mosque, to a hospital, to a stranger, or to an animal. The reward attached to it is described in expansive terms: “The example of those who spend their wealth in the way of Allah is like a seed of grain which grows seven spikes; in each spike is a hundred grains. And Allah multiplies His reward for whom He wills. And Allah is all-Encompassing and Knowing.” (Qur’an 2:261)
A third term you will meet is zakāt al-fitr: a small fixed amount of food, or its value, given by every member of a household before the ‘Īd prayer at the end of Ramadan. It was enjoined as one sā‘ of dates or barley on every Muslim, free or slave, male or female, young or old (Sahih al-Bukhari 1503). It is owed for children too, paid by whoever supports them, and it is the reason ‘Īd morning involves a flurry of last-minute transfers in most Muslim households.
Worth knowing: sadaqa is not restricted to people with money. The tradition explicitly counts helping someone carry something, guiding a lost person, speaking gently, and removing harm from a road as sadaqa — precisely so that being poor never means being unable to give.
Practically: work out zakāt once a year on a fixed date so you do not have to reconstruct it, and treat sadaqa as the thing you do continuously and in small amounts, which is the pattern the tradition praises most.
