The Six articles of Faith, (found in Sahih Muslim) are the belief in:

Allah
To believe in the ONENESS of Allah, swt. (i.e. Tauhid-ar-Rububiyya, Tauhid-
al-Uluhiyya, Tauhid-al-Asma was-Sifat).


Part of the belief in Allah is the belief in all that with which He has described Himself in His Book or with which His Prophet (peace be upon him) has described Him without anydistortion, negation, speculation (as to the exact nature of these attributes), nor analogy (i.e. between Allah's attributes and those of His creation bearing the same names)
Distortion
The Jahmiy (follower of the deviations of Al-Jahm ibn Safwan) negates Allah's statement about himself that he "sat on the throne" by adding an extra letter to the word in the Qur'an.
[Istawaa 'alaa al-'arsh] innovated to [Istawlaa 'alaa al-'arsh]
The innovators who changed the case of a noun in the Qur'an in an effort to negate Allah's attribute of speech:
[Wa kallama Allahu Musa takleeman] innovated to [Wa kallama Allaha Musa takleeman]
Others distorted meanings of Allah's attributes without actually changing the words. Examples include those who said that Allah's anger (Ghadhab) means His intention to punish, His mercy (Rahma) means his intention to have mercy, His hand (Yad) is His generosity or His power, etc.
Negation/Denial (At Ta'teel)
Negation of the Exalted Perfection of Allah Most High via the negation of His Names and Glorious Attributes.
Negation through negation of appropriate interaction with Allah and neglect of worship of Him and obedience to Him, or the association of others with Him in acts of worship and/or obedience.
Negation of the relationship of the creation to its Creator, such as the negation of the philosophers who claimed that this physical universe has no beginning, and that it has always and will always work according to its own internal rules. They turn Allah into an essence with no attributes - which is an impossibility.
Speculation and Analogy (At-Takyeef wa At-Tamtheel)
At-Takyeef means attempts to ascribe a detailed understanding of the exact nature of the various attributes with which Allah has described Himself. Just use the words and understanding given in the Qur'an and not your own philosophies as to what Allah is.
At-Tamtheel means to make a direct comparison or analogy between one of Allah's attributes and a human attribute having the same name, such as the comparison of Isa (Jesus) by the Christians to Allah Most High, or that of Uzair by the Jews or that of the idols by the polytheists to Allah Most High. Likewise the Mushabbiha among the Muslims who compare Allah with His creation by saying that He has a face like our faces, hands like our hands, hearing and sight like ours, etc.


Allah’s angels


Angels are real beings, not illusions, a metaphysical force, or figments of human imagination. They are created from light.
A Muslim must believe specifically in all the angels named and/or described in the Qur'an and the Sunnah:.
Jibreel ("Gabriel"): in charge of delivering revelation.
Mika'il: in charge of bringing the rain.
Israfil: the blower of the horn on Qiyama (Judgement Day).
Malik-ul-Maut: the Angel of Death who takes people's souls at death.
The Noble Recorders: those who record people's actions.
The Protectors (Al-Mu'aqqibat): who keep people from death until its decreed time.
Ridhwan: in charge of Paradise.
Malik: in charge of Hell.
Munkar and Nakir: the questioners in the grave.
The Carriers of the Throne.
Those who record the future of the fetus.
Those who enter the Haram: 70,000 every day.
Those who move about, descending upon gatherings at which Allah and His Book are mentioned and studied.
Belief in the angels is an integral part of iman (faith). [See 2/285 Al-Baqarah]
Kufr (disbelief) with respect to the angels is kufr (a state of disbelief). [See 4/136 An-Nisaa]
