Islam is built on five

The Prophet (may Allah's peace and blessings be upon him) likened Islam to a well-built structure based on five pillars that carry it and the rest of its characteristics complement the structure. First pillar: The two testimonies of faith; testifying that there is no god but Allah and that Muhammad is the Messenger of Allah. These two testimonies constitute one pillar as they are both inseparable. The slave utters the two testimonies of faith acknowledging the oneness of Allah and His exclusive worthiness of worship apart from others, acting upon their requirements, believing in the message of Muhammad (may Allah's peace and blessings be upon him), and following him.

Second pillar: Establishing the prayer, which refers to the five obligatory prayers that are to be observed every day and night and they are: Fajr (morning), Zhuhr (noon), ‘Asr (afternoon), Maghrib (sunset), and ‘Ishā’ (night), along with observing their conditions, pillars, and obligatory acts. Third pillar: Giving the obligatory Zakah, which is an obligatory financial act of worship due on every type of property that has reached the limit prescribed by Shariah and it is to be given to those entitled to it. Fourth pillar: Performing Hajj, which is travelling to Makkah to perform the rituals as a means of worshipping Allah Almighty. Fifth pillar: Fasting Ramadān, which is abstaining from food, drink, and other invalidators from the break of dawn until sunset with the intention of worshipping Allah.
