Does the word "believer" (المؤمن) and the address "O you who have believed" (يا أيها الذين آمنوا) in the Quran refer to everyone who says: "I am a believer" without the intention of the heart? And do "those who have believed" in His saying, the Most High: "those who have believed and whose hearts are assured by the remembrance of Allah" include any believer regardless of their intention, or does it refer to those who have attained complete certainty, like "those who are certain that they will meet Allah"? And what is the measure of faith in our society?

Faith increases and decreases, and its adherents vary in degree. Verse (249) of Surat Al-Baqarah is a proof of this, as it divided the believers with Talut into two categories: a category of great faith and a category of lesser faith. The term "faith" (Iman) in the Quran addresses those who believed in what the messengers brought and submitted to God's law outwardly and inwardly, and they vary in degrees of faith. As for the hypocrites, they are not included in the category of believers. Verse (2) of Surat Al-Hujurat is a discipline for the believers against raising their voices above the voice of the Prophet, peace and blessings be upon him, and it does not include the hypocrites who raise their voices out of disdain. Verse (28) of Surat Ar-Ra'd is a praise for the believers whose hearts are assured by the remembrance of Allah. The address to the believers does not negate the issue of endings; if the description of faith ceases for someone, then they do not fall under the generality of the address.
