The Words: Zakah And Sadaqah
The Meaning Of The Word Zakah In Language And In Shari'ah
Zakah in language is an infinitive of the verb zakah. Zakah means to grow and to increase. When it is said about a person, it means to improve, to become better.
Consequently zakah is blessing, growth, cleanliness, and betterment.1 In Lisan al Arab it is said, "The root of the word zakah in Arabic means cleanliness, growth, blessing, and praise. All these meanings of the word are used in Qur'an and Hadith." It seems to be most obvious according to al Wahidi and others that the root "zakah" means increase and growth. For example, with respect to plants it means to grow and with respect to things, it means to increase. But since plants grow only if they are clean of insects and other detrimental things, then the word "zakah" implies cleanliness and cleansing. If it is used with respect to persons, zakah then means betterment and righteousness. You may say a man is "zaki"; that is, he has good character, or you may say that the judge "zakah" the witnesses to mean he shows that they are of a higher level in their testimony.
In Shari'ah the word zakah refers to the determined share of wealth prescribed by God to be distributed among deserving categories. It is also used to mean the action of payment of this share2. According to al Nawawi's report from al Wahidi, this share of wealth is called zakah because it increases the funds from which it is taken and protects them from being lost or destroyed.
