Is testimony rejected because a person has lost his honor?

Mashhur: Does the loss of honor due to a customary reason, rather than a religious one, lead to the rejection of testimony?

The Shaykh : I did not understand. Please repeat it.
Mashhur: If we rule that a certain person has lost his honor, not due to a religious reason—such as shaving the beard, for example, or going bareheaded, or having a profession that people consider base and which causes the loss of honor—does this reason cause the testimony to be rejected before the judge?

The Shaykh : Now make your meaning clear to me. This depends on our statement: Is the loss of honor that was customary in the past still in effect today? If the custom is still in effect, then the answer is yes, his testimony is rejected. If the custom has changed, his testimony is not rejected.
Mashhur: If a new custom arises from custom, not from the Shari'ah, and it causes the loss of honor.

The Shaykh : The answer is that it is rejected.
Mashhur: The same answer.

The Shaykh : Yes, that is right.
Mashhur: May Allah reward you with good.

The Shaykh : Yes, and may Allah reward you as well, if Allah wills.
And glory be to You, O Allah, with Your praise. I bear witness that there is no deity but You. I seek Your forgiveness and turn to You in repentance.
