The unity factors of the Islamic ummah are:
1.Unity of Aqeedah
Muslims have a system of bringing everyone who speaks the Shahadat sincerely. And whoever does not utter it, then does not belong to this part of the people.
2.Unity of Worship
Allah Almighty says in al-Quran in the letter of adz-Dzariyat verse 56 which means: "And I do not create jinn and man except to worship me".
The worship that God requires of us all is one. Every Muslim is required to pray five times a day a night, fasting in Ramadan every year, zakat when it comes to nishab, and pilgrimage to the Baitullah for the already capable, as for other 3.obligations in Islam.
Unity of Custom and Behavior
In Surat al-Ahzab: 21, Allah Almighty says, which means: "There is indeed a good example of the Messenger of Allah."
4.Unity of History
A Muslim is not bound by a certain homeland or color, and only Islamic history becomes his bond and pride.
5,Language Unity
It is natural that Arabic is one of the unifying factors of Muslims. This does not mean rejection of other languages in the Islamic world. What is demanded is to make Arabic the official language of the Islamic state and the means of communication of Muslims, without denying the local language as a specific communication language.
6.Unity of the Road
Indeed the way of the Muslims is one. That is the way of the Prophets and Apostles.
"Show us the straight path; that is the way of those whom Thou best bestowed upon them; not the way of those on whom You are angry, nor their way of perverting. "(al-Fatihah: 6-7)
7.Unity of Dustur
The source of Muslim law is the Qur'an and as-Sunnah. Muslims are forbidden from taking referrals, to organize and organize their movements on this earth, except from what Allah sent down and brought to his Apostles.
As it appears in the Qur'an in the letter an-Nisa ': 65 and al-An'am: 162-163.
8.Leader Unity
Muslims agree that the first leader is the Messenger of Allah, then the guided caliphs. Each of them became a leader of his day. There can be no Muslim leadership more than a caliph.
