Is it permissible to live in one room with Christians out of necessity, while observing the Sharia regulations?

The relationship with peaceful People of the Book is based on righteousness, justice, and fairness, as Allah says: ﴿Allah does not forbid you from those who do not fight you because of religion and do not expel you from your homes - from being righteous toward them and acting justly toward them. Indeed, Allah loves those who act justly.﴾ [Al-Mumtahanah: 8]. It is permissible for a Muslim to reside with peaceful People of the Book, with the possibility of inviting them to Islam through word and deed, as it is stated in the Hadith: "For Allah to guide a single man through you is better for you than red camels."
