All the worships for the believers are a kind of practice for strengthening their soul and body. In this universe, there will never be a competition or match; in other word, all the human beings are keep practicing in this world until the very last minute of their life. Among these people there are some who are weak and have no tendency to practice their body and soul, these types of people are used to practicing Self-indulgence and never make any efforts. It is as if these people are not eager to practice their souls by worshiping and are not intended to strengthen their souls. But people who are zealous to improve spiritually are people of practice in this world; these people are those who have been praised by Allah Almighty and are referred to as prosperous people. These people are keep practicing and making a lot of efforts so as to strengthen and improve their body and soul until the day when the death angel takes away their soul like a kind father.
