Muslims are allowed to use unbelievers’ utensils after being cleaned from any impurity. It is also permitted to eat from earlier religions people food. The Prophet himself accepted a Jew invitation to a meal.
The primary ruling is that these are permissible to use. However, if it is known that they are contaminated with impurity, then they may not be used until they have been washed.
:Abu Tha'labah al-Khushni reported
‘I said: “O Messenger of Allah, we live among people who belong to earlier religions: is it permissible for us to eat in their plates? ” He said: “Do not eat in their plates. If you find nothing else, wash them and use them.”’

If such plates and utensils are not known to be contaminated with impurity, as in the case when their owners are known to handle no impurity, they are permissible to use.
‘It is confirmed that the Prophet (peace be upon him) and his Companions took water for their ablution from a large waterskin belonging to an idolater woman.’
