In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
If you are a delivery agent for Amazon and your job involves delivering items to church or temple or any other place, you ought to deliver them as honestly as possible.
In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
As a Muslim, you are obligated to fulfill your duties as an employee. Allah tells us that one of the essential traits of the servants of the Merciful is that they are faithful to their covenants and pledges.
This includes, among others, performing our duties at work as efficiently as possible; otherwise, the salary we earn becomes unlawful and impure.
We should earn our salary through honest work. So, if you are a delivery agent and your job involves delivering items to church or temple or any other place, you ought to deliver them as honestly as possible. If you are remiss in it, then your income is earned through unlawful and unethical ways. You cannot make a false claim and refuse to deliver the same.
If you are not happy with the job, you should look for some other job. But as a Muslim, you ought to fulfill your duties as faithfully as possible; otherwise, you are guilty of cheating and fraud.
Remember our beloved Prophet (peace be upon him) took on the job for his wife Khadijah and earned her trust by doing it with integrity. It was his character that made him her faith, and thus she went out of her way to propose to him, even though he was poor!
Almighty Allah knows best.
