I was taught that a wall or any place that has the capability to acquire dirt can be used for tayammum but after going through this answer on What are the materials used for tayammum? which prohibits the walls without a reference and also going listening to a speaker on youtube I came across this new information that walls are not allowed for tayyamum.
- I would like to know if there is a difference of opinion and which madhabs do or do not allow wall as an object of tayammum
- If wall is not allowed, then how would a bedridden person suppose to do? he/she can go to the toilet with great difficulty in the first place so how should he/she prepare oneself(the wudhu replacement) for salah?
perform Tayammum with clean Earth
In my opinion walls/doors ( irrespective of painted or not), are permissible since everything is directly or indirectly is created from products of Earth (example trees, paint polymers etc which are made from materials found on earth itself and not Mars)
