The Ruling on Sitting on a prayer mat that contains a picture of a Masjid:
Ash-Shaykh Ibn Baaz, may Allaah have mercy upon him, was asked on the ruling of sitting on a prayer mat that has a picture of the Masjid al Haraam and Masjid an Nabawee or any other masjid ?
A: It is a must that these prayer mats are not used due to (sitting on it) is consider to be belittling these Masaajids even though it (the masjid ) is not actually present but however (sitting on) the picture is consider to be belittling it. So the least of its affair is being makrooh (disliked).It is a must that it is not used but rather one should use the prayer mats that are free from that (pictures of Masjids) and the worse picture it can be is the picture of the Masjid of the Prophet, alaihi as salaatu was salaam, and what it (his masjid) contains of such as his grave for indeed sitting on the (picture) of his ,alaihi as salaatu was salaam, grave is consider to belittling it and degrading its value even though one may not intend that. So it is a must that these prayer mats are not used and the least of its affair is being makrooh rather one should use the prayer mats that are free from that (pictures of Masjids).
