5- The Effects of Aqeedah on the Practical Life of Muslims
When a person’s aqeedah (belief) is correct, then his actions are certainly correct and proper as well, because aqeedah is something that guides a Muslim towards goodness and righteous deeds. The testimony of the Oneness of Allah given on the basis of knowledge and action becomes a means for good deeds, because it is not merely the utterance of words by the tongue, but in reality, it is the expression of one’s belief and actions. Without practical expression, this testimony is not beneficial.
