Is it permissible for an employer to make a worker swear on the mushaf that he will not be treacherous and will not steal?

Question:
He says: Honorable Shaykh, may Allah grant you success. If an employer asks a worker in his employ to swear by Allah that he will not be treacherous to him and will not steal from him, and this is before starting the work, what is the ruling on this request and condition? What is the ruling regarding the worker? And what is the ruling if he asks him to swear on the mushaf regarding this matter?

Answer:
Swearing on the mushaf is not prescribed. This is something the common people have become accustomed to, meaning they have taken the mushaf for the purpose of swearing on it. However, if he conditions his worker to this or makes him swear to it, there is no harm in that. He is seeking assurance from him in order to verify this.
