Faith is the bedrock of belief in the life of a Muslim. Everything he does revolves around faith. The lenses with which he sees the world is the lens of faith. His thought process is powered by faith. It is for this that scholars have said that the completion of faith is threefold and they are as follows:
1. Conviction in the heart: Allah says in the Qur’an
“When the hypocrites come to you (O Muhammad SAW), they say, ‘We bear witness that you are indeed the Messenger of Allah.’ Allah knows that you are indeed his Messenger and Allah bears witness that the hypocrites are liars indeed.’” (Munafiqun 63:1)
From this ayah, we can see that faith doesn’t end on the tongue. There has to be a conviction in the heart that distinguishes one from hypocrisy. May Allah save us from hypocrisy.
2. Declaration with the tongue: Now, faith doesn’t end in your heart. You have to testify in your speech and your speech testify for you. If Iman was fine in the heart alone, then the Pharaoh is a Muslim, because he believed in Musa’s God but still, because of his arrogance, he died a kafir.
3. Implementation with the limbs: It is not enough to be a Muslim by speech and in the heart alone. We have to show it in our actions. If we believe Iman is simply conviction in the heart and declaration with the tongue, then we are saying that Shaytan is a Muslim because he is convinced Allah is Lord, he has declared it in his speech, but what he has failed to do is implement with the limbs. Allah says:
“And when We said to the angels: ‘Prostrate yourselves before Adam’. And they prostrated except Iblis (Shaytan), he refused and was proud and was one of the disbelivers”
