Sometimes the time for prayer comes and
I am in the house of one of the Christians, so I take my prayer mat and pray in front of
them. Is my prayer valid even though I am in one of their houses?
Yes, your prayer is valid. May Allaah make you even more keen to obey Him, especially with regard to performing the five daily prayers on time. It is the Muslim’s duty to try to pray them in congregation, and to pray them in the mosque whenever possible.
