[Q]: How does the correct ʿaqīdah (creed) reflect in the Muslim’s life and actions?

[A]: If the ʿaqīdah is correct, the rest of the Muslim’s actions will be correct. That is because the correct ʿaqīdah evokes the Muslim to perform righteous actions, directing him to goodness and praiseworthy deeds. If one were to testify that none has the right to be worshipped in truth but Allāh (Lā Illāha Illá Allāh)—that testimony being founded upon knowledge, certainty and awareness of what it entails—then it would direct him to perform righteous actions. For the testimony of Lā Illāha Illá Allāh is not a mere utterance said with the tongue. Rather, it is a proclamation of belief and action. Moreover, this testimony is not considered correct nor will it benefit an individual unless they uphold what it entails of righteous deeds. Hence, they perform the pillars of Islām, Īmān, and the additional commandments of the religion, its legislations, recommended acts and complements.
