In Islam, faith and good works go hand-in-hand. A mere verbal declaration of faith is not enough, for belief in Allah makes obedience to Him a duty.
The Muslim concept of worship is very broad. Muslims consider everything they do in life to be an act of worship, if it is done according to Allah’s guidance.
There are also five formal acts of worship which help strengthen a Muslim’s faith and obedience.
They are often called the “Five Pillars of Islam”.
