What is the wisdom behind the impermissibility of a Muslim praying in a room that contains statues and pictures on the walls, such as pictures of Christmas wreaths?

Scholars have agreed on the prohibition of praying in a place where there are images of living beings. Some considered it haram (forbidden), while the majority deemed it makruh (disliked).

Al-Nawawi said: "It is disliked to pray in, towards, or on clothing that contains images, a cross, or anything that distracts."

Ibn Taymiyyah stated that Umar ibn al-Khattab, may Allah be pleased with him, and others did not enter churches that contained images, and that angels do not enter a house where there are images.

Al-Bahuti al-Hanbali considered it disliked to pray facing a fixed image because it resembles the prostration of disbelievers to it. It is also disliked to pray facing a wall with an image or statues, due to the resemblance to idol worship.

The Permanent Committee mentioned that praying in a place where there are images in front of the worshipers resembles idol worship, and they stated that hanging images of living beings is impermissible.

Late Hanbali, Hanafī, and Shāfiʿī jurists—unlike some others—emphasized the prohibition of praying in a place with images, even if they are behind the worshiper or laid on the ground.

Al-Shabramallasi al-Shafi'i mentioned that it is disliked to pray in clothing that has an image or to pray on it.

The wisdom behind prohibiting prayer in a place with images and statues: 1. Angels do not enter a house where there are images: Based on the Prophet Muhammad's (peace be upon him) saying: "Angels do not enter a house in which there is a dog or statues with images." A worshiper seeks mercies and blessings, so it is not appropriate to seek them in a place that angels of mercy do not enter. 2. Avoiding resemblance to idol worshipers: The Sharia came to enjoin avoiding resemblance to non-Muslims to preserve the Muslim's identity. 3. Avoiding distractions for the worshiper: Images can distract the worshiper and occupy their thoughts. A Muslim strives for complete khushu' (devotion) in their prayer, as the Prophet (peace be upon him) said to Aisha regarding her patterned curtain: "Remove this patterned curtain from us, for its patterns keep presenting themselves to me during my prayer."
