Aqidah (Creed/Belief) refers to the core articles of faith that a "Mu'min" must hold with absolute "Yaqin" (certainty), including belief in Allah, His Angels, Books, Messengers, the Day of Judgment, and "Qadar" (destiny). For the "Ummah," a sound "Aqidah" is the foundation of all "Amal" (deeds). It provides the spiritual and intellectual framework that protects the believer from "Shubuhut" (doubts) and "Fitna," ensuring that their "Ubudiyyah" (servitude) is directed solely toward the Creator. The six pillars of aqidah are derived from the Quran and Hadith. Belief in Allah includes belief in His existence, His oneness (tawhid), His attributes, and that He alone is worthy of worship. Belief in the angels includes belief in their existence, their roles, and that they are honored servants of Allah. Belief in the Books includes belief that Allah sent down scriptures to previous prophets and that the Quran is the final, preserved revelation. Belief in the Messengers includes belief that Allah sent prophets to guide humanity, and that Muhammad (peace be upon him) is the final messenger. Belief in the Last Day includes belief in death, the grave, resurrection, judgment, Paradise, and Hell. Belief in Qadar (divine decree) includes belief that Allah knows all, has written all, and wills all that occurs, while affirming human responsibility. Aqidah is not just intellectual assent but belief that transforms the heart and actions. The Quran describes the believers: "The believers are only those who, when Allah is mentioned, their hearts become fearful, and when His verses are recited to them, it increases them in faith" (8:2). A sound aqidah is essential for correct worship. Acts of worship without correct belief are meaningless. The Quran says: "And indeed, it has been revealed to you and to those before you: 'If you associate partners with Allah, your deeds will become worthless'" (39:65). Aqidah also protects from deviation. When one understands the attributes of Allah, they are not confused by theological doubts. When one believes in the Hereafter, they are not consumed by worldly temptations. The early scholars emphasized the importance of aqidah. Imam Abu Hanifa wrote a work on aqidah (al-Fiqh al-Akbar). Imam al-Tahawi's creed (al-Aqidah al-Tahawiyyah) is a standard text. For believers, aqidah is the foundation. They learn it, internalize it, and defend it. They seek certainty (yaqin) in their beliefs, not doubts. They know that without sound aqidah, deeds are not accepted. The ultimate aqidah is the belief that leads to Paradise. The believer holds firmly to the creed of the early generations (salaf), following the Quran and Sunnah, and avoiding innovation (bid'ah). They strive to live their beliefs, making their aqidah manifest in their actions, their character, and their devotion to Allah.
