Then He replaced them with those who believed, meaning they manifested this description. Their hearts find tranquility, meaning they settle and feel at ease with the evidence after the disturbance caused by doubts. They find reassurance after the state of faith, in a continuous manner indicating the stability of their faith to abandon obstinacy. This present tense in this construction is not intended to indicate a state or a future, rather it is intended to indicate continuity of meaning while disregarding the times. By the remembrance of Allah, which is the greatest of signs, for the mentioned is one that encompasses the attributes of perfection. The verse contains an implication: the mention of will first indicates its omission second, and the mention of repentance second indicates the omission of its opposite first.

And when this is a place for the obstinate to say: 'And who finds tranquility in that?' It is said: 'Indeed, by the remembrance of Allah,' meaning the One who has majesty and honor, not by the remembrance of others. The hearts find tranquility, so they cease seeking the evidence of others. The remembrance is the presence of meaning in the soul, and this is an indication that whoever does not find tranquility in it has no heart, let alone having reason in his heart. Rather, he is among the inanimate, or that every heart finds tranquility in it. So whoever reports about his heart contrary to that is a lying obstinate, and whoever submits and acts according to what brings reassurance is a believer.
