Imam Ali (AS) narrated from the Prophet of Islam (PBUH) who said:

How prosperous is the person who is Muslim, and has normal livelihood and his/her forces are standing up [1]. Imam Ali (AS) commented on the Prophet of Islam’s (PBUH) sentence by saying: How prosperous is the one who has the following three characteristics. Firstly he/she is a Muslim and a believer. Secondly he/she is able to cover or earn the normal life expenses. And thirdly be healthy and his/her forces are in their right places. The above mentioned cases are the least required for a prosperous life [2].
