A---信仰必须通过言语和行为来表达。言语必须发自内心并以口说出，行为也是如此，必须由身体相应的器官来完成。人服从真主时信仰增长，违抗真主时信仰减弱。每个人的信仰强弱各不相同。

A--- Faith must be expressed in words and deeds. The words must come from the heart and uttered orally, and this also goes for the deeds, which must also be done by the relating organs of the body. Faith increases when one obeys Allah, and decreases when he sins against Him. Strength of Faith varies from one person to another.
