The Quran says worship God and be patient in God's worship (19:65). Another verse in the Quran says, "I created the jinn and mankind only so that they might worship Me." (51:56) This means that the purpose of our lives is to worship God. Here 'worship' is not only in the sense of performing rituals, but is rather meant in the greater sense. That is, your whole life should reflect that you are a believer and worshipper of God.Worship is the purpose of life and the Quran itself says that worship cannot be possible without being patient. So to fulfil the purpose of our lives we need keep patience. If we do not remain patient, we will not be able to do what we have been created for.
