What is the ruling on my suckling from a woman who claimed to have suckled me after she refused to suckle me when I needed it?

Jurists have differed regarding the acceptance of the testimony of a single woman concerning fosterage (rada'ah). The preponderant opinion is that her testimony is acceptable if she explicitly states that she breastfed the questioner five times within the two-year suckling period; otherwise, the fosterage is not considered valid.
