What is the ruling on a disbeliever uttering the two testimonies out of fear of harm?

Question:
What is the ruling on one of the disbelievers who says: "There is no god but Allah," because he fears that it will harm his earnings? Does it harm him or not?

Answer:
If he does not affirm the oneness of Allah and says: "There is no god but Allah," he should be stopped until his case is examined, just as the Prophet (peace and blessings be upon him) ordered Usamah to do.
As for one who speaks of the oneness of Allah but does not stop associating partners with Allah, his words are of no benefit. He must abandon shirk (associating partners with Allah) and repent from it. Thus, the worshippers of al-Badawi, the worshippers of al-Husayn, the worshippers of 'Ali, or the worshippers of al-Lat, or the worshippers of the stars, or the worshippers of idols, if they say it—meaning: "There is no god but Allah"—they are not to be stopped until they repent from their deeds, until they repent from their shirk (associating partners with Allah) and disbelief. Likewise, one who insults Allah or insults the Messenger (peace and blessings be upon him) while saying: "There is no god but Allah," is not to be stopped until he repents from this.
