Question: The committee was asked about prayer in the workplace, in a room that has pictures of people hanging on the wall in front of them. Is the prayer valid and should they continue praying in such a place?
Response: The prayer is valid, and this does not harm them, in shaa.-Allaah, if they were pressed to pray in such a place, due to the absence of a nearby masjid. However, it is binding on them to do their best working with their supervisors to remove the pictures from this place, or to provide another place that does not have pictures, since prayer in a place that has pictures in front of the people is a kind of imitation of the worshipers of idols, and a number of narrations have come showing the prohibition of imitating the enemies of Allaah and the order to oppose them. Also, one should know that hanging pictures of things with souls on the walls is an affair that is not permissible, it is from the avenues of excessiveness and shirk, especially when they are pictures of honoured people. And we ask Allaah to grant success and guidance to all.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu `alayhi wa sallam) and his family and his companions.
