Kabeer, you are talking irrelevant things. the abrasice mark on the forehead is due to the place where they do sajda. In saudi most of the mosques carpeted. In India it will be mat or tiled floor. Indian mosques mostly do not have carpets or soft floor. Did ever lord krishna claimed that he is god of hindus?
Hindu is the name given by muslims. still you keep that name only. better find out what religion lord krishna was talking. name your religion the same name and call lord krishna your god
