Is it permissible for a Muslim woman to continue her work, which requires her to cook pork and use white wine, out of necessity to secure a livelihood for her family in a non-Muslim country, knowing that those who benefit from this work are not Muslims?

The questioner (sister) is advised to return to her country unless there is a necessity for her to remain, as there is a prohibition against residing in lands of disbelief (Kufr) due to the resultant temptation (fitna) in matters of religion.

What she mentioned regarding the poor economic conditions is not considered a necessity, especially since she has found similar conditions in the lands of emigration.

Perhaps if she intends her return for the preservation of her religion and the religion of her children, Allah will provide her with a way out and good sustenance, for Allah Almighty says: "And whoever fears Allah - He will make for him a way out And will provide for him from where he does not expect."
