Aqidah (sometimes spelled Aqeeda, Aqidah or Aqida) (Arabic: عقيدة plural عقائد 'aqā'id) is an Islamic term meaning creed. Any religious belief system, or creed, can be considered an example of aqidah. However this term has taken a significant technical usage in Muslim history and theology, denoting those matters over which Muslims hold conviction. There are three main accepted schools of Sunni Aqidah: Ashari, Maturidi and Athari.
For example, Muslims may have different ideas regarding the attributes of God or about the purpose of angels. However, there is no dispute on the existence of God, that he has sent his revelation via messengers nor that man will be held to account and rewarded or punished with heaven or hell.
Six articles of belief
In the Hadith Sahih Muslim and Sahih al-Bukhari, the Islamic prophet Muhammad explains, "It (Al-Iman/faith) is to affirm your faith in Allah, His angels, His Books, His Messengers and the Last Day, and to believe in the Divine Destiny whether it be good or bad."
The six Sunni and Shia articles of belief are:
- Belief in God (Allah), the one and only one worthy of all worship (tawhid).
- Belief in all the Prophets (nabi) and Messengers (rusul) sent by God
- Belief in the Angels (mala'ika).
- Belief in the Books (kutub) sent by God (including the Qur'an).
- Belief in the Day of Judgment (qiyama) and in the Resurrection (life after death).
- Belief in Destiny (Fate) (qadar).
In Sunni and Shia view, having Iman literally means to have belief in Six articles. However the importance of Iman relies heavily upon reasons. Islam explicitly asserts that belief should be maintained in that which can be proven using faculties of perception and conception.
Shi'a beliefs and practices
Roots of Religion (Usūl al-Dīn)
- Tawhīd (Oneness): The Oneness of Allah.
- Qiyamah (The Day of Judgment): Allah will raise mankind for Judgment
- Nubuwwah (Prophethood): Allah has appointed perfect and infallible prophets and messengers to teach mankind the religion (i.e. a perfect system on how to live in "peace".)
- Adalah (Justice): The Justice of Allah.
- Imamah (Leadership): God has appointed specific leaders to lead and guide mankind — a prophet appoints a custodian of the religion before his demise.
Branches of Religion (Furū al-Dīn)

Many Muslim scholars have attempted to explain Islamic creed in general, or specific aspects of aqidah. The following list contains some of the most well-known literature.

- Aqeedah al-Waasittiyah by Ibn Taymiya.
- Sharh as Sunnah or the Explanation of the Creed by Al-Barbahaaree. Lists approximately 170 points pertaining to the fundamentals of Aqidah.
