Can narrators who listen to singing, such as Yusuf ibn Ya'qub al-Majishun and his family, be trusted, even though they are described as "trustworthy in hadith, whose narrations are included in the Sahih collections"?

The narration of someone who listens to music is accepted from trustworthy individuals if he is mutawwil (interpreting it as permissible), meaning he believes in its permissibility. This is affirmed by scholars. The mutawwil transgressor who is unaware of his own transgression—especially if his transgression is merely presumed—his narration and testimony are accepted. Al-Shafi'i mentioned the acceptance of the testimony of a Hanafi who drinks nabidh (a type of fermented drink) because his transgression is not definitively established. As for the transgressor who is not mutawwil, his narration and testimony are rejected by the consensus of scholars.
