Would the suckling be established by the statement of a woman known for lying, which would lead to the prohibition of a young man's engagement to a girl?

Scholars differed regarding establishing fosterage (رضاع) with the testimony of a single woman. The preponderant opinion is that it is established by the testimony of a single, trustworthy woman who is not accused [of lying], based on what Al-Bukhari narrated from Uqbah ibn Al-Harith, may Allah be pleased with him. Accordingly, the statement of a woman known for lying is not accepted in a claim of fosterage. Nevertheless, it is advisable to proceed cautiously and consider circumstantial evidence. If her statement has some validity, then refraining from the marriage proposal out of precaution is a good thing. However, the dissolution of an established marriage should not be undertaken based on the word of such a woman.
