Right actions are deeds, which are performed utterly in order to earn the good pleasure of Allah. A person may perform some actions which seem to be remarkable in their goodness or self-sacrifice. For instance, he may give considerable amounts of help, money etc. to those in need. The amount of his aid, however, does not indicate that it is a right action because people may provide such help in order to be known as "good" by others, or to show off or to gain people's trust in a business transaction. For a deed to be a "right action", it should be performed only to please Allah.
One exerts oneself to do one's best while performing right actions not because one's aim is to show off, but to attain the result which would please Allah the most. On account of these sincere efforts, Paradise and a good life are promised to believers who do good deeds:
As for those who believe and do right actions and humble themselves before their Lord, they are the Companions of Paradise remaining in it timelessly, for ever. (Surah Hud: 23)
Anyone who acts rightly, male or female, being a believer, We will give them a good life and We will recompense them according to the best of what they did. (Surat an-Nahl: 97)
