The ruling on one who pronounces the two testimonies of faith and then apostatizes

Question:
This man says:

Answer:
He says: If a person pronounces the two testimonies of faith, he is a Muslim. We say: Yes, if a person pronounces the two testimonies of faith, he is a Muslim. But if he does something that contradicts the testimonies and negates them, we rule that he has apostatized. If he calls upon other than Allah, or slaughters for other than Allah, or seeks aid from the dead, or deliberately abandons the prayer, we say: This person said "There is no god but Allah" and entered Islam, but he apostatized. He apostatized by abandoning the prayer, or by shirk (associating partners with Allah) through calling upon other than Allah, or slaughtering for other than Allah, or making a vow for other than Allah. So he has invalidated his Islam; he has invalidated his Islam. Yes. Allah (Exalted and Majestic) says: . Do not invalidate your deeds by doing something that invalidates them. Rather, continue in Islam and in the deeds of Islam, and do not do anything that invalidates Islam. Islam is invalidated by the nullifiers that corrupt it.
