Prayer is one of the five pillars of Islam that every Muslim must do. Prayer is worship that is carried out by standing, bowing, prostrating, sitting and standing which are carried out repeatedly according to the specified amount of time. Prayer is done five times a day and is a means to unite oneself with God.

The law of praying is obligatory. This means that every Muslim who has reached puberty (adult) and is of sound mind is required to pray five times a day, namely the morning prayer, midday prayer, Asr prayer, Maghrib prayer and Isha prayer. If someone does not perform the prayer without a reason that is accepted by the syar'i, then he is considered to have committed a sin. However, if a person is unable to pray due to illness or other reasons that are accepted by the syar'i, then he is not considered a sinner.
