Is it permissible to use ceramic instead of mud brick in construction when strong clay is available?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: In our province, a type of lightweight ceramic is used instead of mud brick. Is this action permissible?

Answer:
No, that would open the door to this. Ceramic bricks are only placed to take the place of mud brick when mud brick is not available, when there is no strong clay or the like. There is no harm in that. But as long as strong clay is available, mud brick is made from it. We do not open this door, for the Sunnah would be changed and they would alter it, and perhaps they would bring in things that are not permissible. Yes.
