A person forced another to give false testimony; does the witness owe an expiation?

Question:
May Allah reward you. The sender is Muhammad Soudin Hamad al-Fahd from the Hashemite Kingdom of Jordan. He sent a number of questions, saying in the first: My brother left the house, and he had a pressing need. When he reached the place of his need, he met a man he knew, and the man forced him to testify regarding riba (usury or interest). His intention was not to sign or testify, but he feared him. Does he owe an expiation? If he does owe an expiation, what is its amount? And what do you advise? May Allah reward you with good.

Answer:
This is forbidden testimony, and it is not permissible to obey the created in disobedience to the Creator. This is false testimony, forbidden testimony, based on the saying of the Messenger (peace and blessings be upon him) Thus, the two witnesses are included among those upon whom the curse falls. Because they validated this riba with their testimony and cooperated in sin and aggression, it is obligatory for him to repent to Allah and to invalidate his testimony. He should go to the scribe who wrote his testimony, or to the judge if it was validated in a court, and go to invalidate his testimony. Yes.
