Is marriage forbidden based on a wet nurse's testimony, whether truthful or false?

Scholars differ on accepting the testimony of a single nursing woman to establish prohibition (of marriage). The majority do not accept it, whereas the Hanbalis accept it on the condition that the woman is righteous, meaning characterized by truthfulness and uprightness. Her testimony is not accepted if she is known to be a liar. Consequently, marriage is not prohibited based on the testimony of a woman if she is not known for truthfulness.
