Dear Hadi,
Dear Reader,
Thank you for your question. We believe, and God knows best, that the presence of another religion’s statue or religious symbol in a room does not make salah invalid. A Muslim is not worshipping the statue, nor praying to it; they are worshipping Allah SWT alone. The important distinction is between the object being present and the worshipper directing their prayer toward it or venerating it.
That said, if it's possible to avoid praying directly toward the statues, images, or religious symbols, then that may be best so as not to be distracted by their presence. One situation where we see this may arise is in airport prayer rooms. You may know that some airports have multi-faith or multi-denominational prayer rooms intended for people of different religions. Such a room may contain religious symbols or even statues associated with another faith. If a Muslim wants to say their prayers there, in our opinion, the mere presence of the statue does not mean the Muslim is worshipping it or that the prayer is invalid, and Allah SWT knows best. The Muslim should simply face the qiblah, not the statue (if possible), and pray to Allah SWT alone.
The same principle applies in other public spaces: a room does not become a place of worship of another religion simply because a statue or symbol is present. What matters is what you are doing and what you believe. You are not bowing to the statue, invoking it, or seeking help from it; you are praying to Allah SWT, and isA will have that devotion to prayer counted among your good deeds.
In peace.
