Is it permissible to pray in abandoned and old houses?

The prayer of a Muslim in the aforementioned houses is valid, based on the saying of the Prophet, peace and blessings be upon him: "The earth has been made for me a mosque and a means of purification, so wherever a man from my Ummah is overtaken by prayer, he should pray." Even if the house is usurped, prayer therein is valid according to the majority of scholars. However, the permissibility of proceeding to pray in it or reside in it cannot be judged, due to not knowing the reason for the residence.
