In plain words
Muslim worship: 'Faithfulness in God, trust in the Prophet.' Having self-confidence, placing the whole burden upon God and remaining so, and recognizing the divine power at every step — these are the principal precepts in the world. Having performed the abandonment of the body [death], afterwards proving one's own truth in God's court in the world beyond — this too [is a principal precept]. That is to say, keeping upright conduct befitting that right up to the end of one's life. Practising to the letter the teachings of the scripture that is the voice of God, the Qur'ān. These are the precepts concerning the world beyond in Muslim worship.
