There are rules of islam that muslim must belive them,Islam consists of five basic pillars that the Muslim believes in and works in until he becomes a Muslim. It shows the importance of the meeting of the five pillars to define a Muslim in the Prophetic hadith. The Messenger of God, peace and blessings be upon him, said: “Islam is built on five: Shahada That there is no god but God, and that Muhammad is the Messenger of God, establishing prayer, giving zakat, pilgrimage to the House, and fasting Ramadan” (Bukhari and Muslim).

1- The first rule of the rules of islam is  Shahada

That a person believes that God alone is the Lord, the Owner, the Controller, the Creator, the Sustainer, and he affirms for him all the Most Beautiful Names and the Highest Attributes that He affirmed for himself, or that His Messenger affirmed for him, and believes that God alone is worthy of worship and no one else.

The person also believes that God sent His Messenger, Muhammad, may God’s prayers and peace be upon him, and revealed the Qur’an to him and commanded him to communicate this religion to all people, and believes that loving God and His Messenger and obeying them is obligatory for everyone.

2- The second rule of the rules of islam is salah

That a person believes that God has enjoined upon every sane adult Muslim five prayers a day and night that he performs in a state of purity, so he stands before his Lord every day pure, humbled and humiliated, thanks God for His blessings, asks Him of His bounty, asks Him for forgiveness from his sins, asks Him for Paradise and seeks refuge with Him from Hellfire.

The obligatory prayers for the day and the night are five prayers: Fajr, Dhuhr, Asr, Maghrib and Isha. There are sunnah prayers such as qiyaam al-layl, and Tarawih prayer. And two rak’ahs forenoon and other Sunan.

 2- The third rule of the rules of islam is zakat

God created people with different colours, morals, science, business, and livelihood, so He made the rich and the poor among them to test the rich with gratitude and the poor with patience.

Since the believers are brothers, and brotherhood is based on kindness, benevolence, compassion, love and mercy, God has enjoined upon Muslims zakat to be taken from their rich and given to the poor.

Zakat purifies and develops money, purifies souls from miserliness and miserliness, and strengthens love between the rich and the poor, so that hatred will disappear, security will prevail, and the nation will be happy.

4- The fourth rule of the rules of islam is fasting Ramadan

Fasting is abstaining from the things that break the fast from eating, drinking and having intercourse from dawn to sunset with the intention of fasting.

And patience of faith like the head of the body . And God has enjoined fasting on this nation one month in the year to fear God and avoid what God has forbidden and to get used to patience, restrain oneself and compete in generosity, generosity, cooperation, sympathy, and compassion.

The month of Ramadan is a great month in which God revealed the Qur’an and multiplied the good deeds, alms and acts of worship, and in it the Night of Decree, it is better than a thousand months in which the gates of heaven are opened and the gates of Hell are closed, and the devils are chained.

5- the Fifth rule of the rules of islam is Hajj

God has made Muslims a direction of prayer and supplication wherever they are, and it is the ancient house in Makkah Al-Mukarramah. A sane adult Muslim is able to visit his ancient house, circumambulate it, and perform the rituals of Hajj as indicated by God and His Messenger.

Hajj is a season in which the unity of Muslims, their strength, and their might are manifested. The Lord is one, the Book is one, the Messenger is one, the nation is one, the worship is one, and the clothes are one.
