Q: My old age mother sits on one chair and do sajda on another chair in front of her. Is that a correct way of performing salah?
A: The way your mom is making salaah is incorrect. She must not make sajda on another chair. She should just bend forward more than ruku for sajda. There is no need for her to put her forehead on something for sajda.
But if you can’t explain her or she doesn’t want to accept then leave her to make her salaah that way. Maybe Allah Ta’ala will accept.
