Question
What is the ruling on praying on a padded prayer rug for someone who has knee pain and was advised by a doctor to use this rug?
Answer
I say, and with God's guidance: It is permissible to pray on a padded prayer rug, but the place of prostration requires that the forehead rests firmly, and this may not be achieved with a padded rug, so you should take that into consideration, and God knows best.
