Is it forbidden to step on an image of the Kaaba and holy places depicted on a prayer rug, and what is the jurisprudential opinion regarding boycotting the purchase of such rugs to avoid stepping on them?

There is no harm in photographing inanimate objects, such as the Kaaba, as long as the images do not include living beings. However, a worshipper should not have any images in front of them or on their prayer rug, so as not to be distracted by them. Indeed, the Prophet, peace and blessings be upon him, forbade praying in a patterned garment (khamisah) because its patterns distracted him from his prayer. The intent here is the dislike of praying on these decorated prayer rugs, not out of disrespect for sacred places. Sheikh Ibn Uthaymeen emphasized that prayer rugs with images of mosques should not be placed for the Imam. As for the Permanent Committee, they held that drawings and decorations in mosque carpets distract the heart from the remembrance of Allah and diminish the worshippers' devotion, so mosques should be kept free of them. Nevertheless, prayer performed on them is valid. The Committee also stressed the impermissibility of placing a cross on mosque carpets or elsewhere, and the necessity of removing it.
