What is the ruling on a barber's testimony in Islamic law?

The testimony of a barber is valid and legally accepted if the conditions for testimony are met, such as being a Muslim, being upright (adil), being free from immorality (fisq), and if there are no impediments to his testimony. If he is immoral due to committing major sins or persistently committing minor ones, then his testimony is rejected because of his immorality, not because of his profession. The profession does not affect the testimony, according to the preponderant opinion of scholars.
