What is the validity of the statement that saying "La ilaha illa Allah" alone is sufficient, without action?

Question:
What is your advice to the one who says, "It is enough for me to say La ilaha illa Allah, and it does not harm me to abandon the prayer or the zakah, or to fall into riba (usury or interest), zina (unlawful sexual intercourse), lying, and cheating, for Allah is the Forgiving, the Merciful"?

Answer:
This is a liar, this is a liar. No, there is no god but Allah is merely a phrase spoken with the tongue, a phrase spoken with the tongue, a belief in the heart, and an action with the limbs. They testify to the truth. He said: There is no god but Allah, and they know. They know its meaning and act upon it. So "There is no god but Allah" is not just a phrase. The hypocrite says "There is no god but Allah" while he is . The hypocrites say "There is no god but Allah," but because they did not believe it in their hearts, they are in the lowest depth of the Fire. So it is not just a phrase spoken with the tongue only. Yes.
