In the Qur'an, the word charity when viewed from its meaning as an act. The word amal is close to several other words or expressions, such as fi'il, sa'yu, shan'u, kasab, and jarah. The similarity between all these expressions is that they all include human actions. But even though they are close in meaning, each has a meaning focus
different.
For example, between the words charity and fi'il. Amal has a more specific meaning than the word fi'il. The word charity only specifically refers to the actions of humans and animals, while the term fi'il is also used to refer to the actions of inanimate objects.
The term charity then derives from the word mu'amalah. A term with wazan which shows the meaning of the relationship/rules of behavior between one human being and another human being. The term mu'amalah is very popular in the study of Islamic law, when it distinguishes between human behavior related to God and its relationship with fellow humans (the relationship with God is called worship and the relationship with humans is called mu'amalah).
This derivation from the word charity to the term mu'amalah gives additional meaning to the term charity that in it there is an inevitability of actions that bring people together with other humans. From here, charity-muamalah is sometimes equated with the terms morality and ethics, because everything is considered to be related to the discussion of the rules of conduct contained in the relationship between fellow human beings.
In addition, Charity in the form of masdar has the meaning of actions caused by doing activities, namely 'amila. This understanding can be understood, for example from the verses of the Qur'an below:
Except those who repent, believe and do righteous deeds; So Allah replaced their evil with good, and Allah is Most Forgiving, Most Merciful. QS al Furqon (25) verse 70
