Delivering Fraudulent Merchandise

Q: I work with a Muslim who imports foodstuff and medicine. Sometimes the products are expired and the workers are told to alter the date of expiration to a later date. My job is delivery so I have to deliver these expired goods. Is it halal for me to keep this job? I am also afraid that I may also be asked to alter the dates sometime. What to do?
Allah Ta’ala says, “And do not aid in sin.” (Al-Maaidah). Rasulullah SAW said, “Whosoever deceives is not from amongst us.” (Tirmidhi)
To change the expiry dates of products and sell them is deception. Also to deliver such products will be assisting in sin.

and Allah Ta’ala Knows Best
