What is the ruling on transporting food to a nightclub or a liquor store, knowing that refraining from doing so might lead to dismissal from work?

Delivering food orders to places of immorality is considered aiding in sin, as mentioned by Sheikh al-Islam Ibn Taymiyyah. Therefore, one must refrain from doing so, even if it leads to losing one's job, unless the person is in need of staying in it to earn a livelihood for himself and his dependents and cannot find any other work. And whoever gives up something for the sake of Allah, Allah will compensate him with something better, and sustenance is from Allah.
