The testimony of the Islamic faith is:
‎لا إله إلا الله محمد رسول الله
lā ʾilāha ʾillā-llāh, muḥammadur-rasūlu-llāh
”There is no god but Allah. Muhammad is the messenger of Allah”
This is explained in the following two parts:

The first part of the testimony (shahada) is “There is none worthy of worship except Allah” which is the belief that Allah is One in His Lordship, One in His Worship and Unique in His Actions, Names and Attributes.

The second part of the testimony (shahada) is the belief that Muhammad (peace be upon him) is his slave and the final Messenger of Allah.

Salat (ṣalāh) is the Islamic prayer. Salat consists of five daily prayers which are performed at different parts of the day. All of these prayers are recited while facing in the direction of the Kaaba in Mecca and forms an important aspect of the Muslim Ummah (community). A Muslim may perform their prayer anywhere, such as in offices, universities, etc. However, the mosque is the more preferable place for prayers because the mosque allows for fellowship.

Obligatory Charity (Zakāt) is the compulsory giving of a set proportion of one’s wealth to charity.
Giving of 2.5% of one’s wealth each year to benefit the poor.
Zakāt is obligatory for all Muslims who are able to do so

Fasting is an obligatory act during the month of Ramadan. Muslims must abstain from food and drink from dawn to dusk during this month, and are to be especially mindful of other sins. Fasting is necessary for every Muslim that has reached puberty (unless he/she suffers from a medical condition which prevents him/her from doing so).

The fast is meant to allow Muslims to seek nearness and to look for forgiveness from God, to express their gratitude to and dependence on him, atone for their past sins, and to remind them of the needy. During Ramadan, Muslims are also expected to put more effort into following the teachings of Islam by refraining from violence, anger, envy, greed, lust, profane language, gossip and to try to get along with fellow Muslims better. In addition, all obscene and irreligious sights and sounds are to be avoided.

The Hajj is a pilgrimage that occurs during the Islamic month of Dhu al-Hijjah to the holy city of Mecca. Every able-bodied Muslim is obliged to make the pilgrimage to Mecca at least once in their life.
