Which concept refers to the belief in angels as messengers of Allah?

The belief in angels as messengers of Allah is encapsulated in the concept of Malaikah. In Islamic theology, Malaikah refers specifically to angels, who are considered to be agents of divine will, providing guidance, protection, and messages from Allah to humanity. This understanding is fundamental in Islam, as angels play a critical role in various aspects of faith, including the delivery of revelations, such as those brought to the Prophet Muhammad.

Other concepts mentioned focus on different aspects of Islamic belief. Akhirah refers to the afterlife or the belief in resurrection and judgment after death. Nubuwwah pertains to prophethood and the role of prophets in conveying Allah's message to humans. Kutub designates the holy books or scriptures, which include the Quran and other sacred texts. While each of these terms is important in Islamic teachings, they do not specifically relate to the concept of angels as messengers in the same way that Malaikah does.
