I will tell you in my family there are some uncle of mine who are Shia and I am a Sunni and they use a turbah you must know a clay tablet from Karbala and it is in their Jafari Fiqh that one should only prostrate on a clean earth so they say it is convenient to have a turbah. They sometime tell me to use it. None has given me answer of this and I want to know if it would make my salah makrooh or will it make any difference if we people from Ahl Sunnah prostrate to Allah on a clay tablet.
Answer
(Fatwa: 1124/944/B=1433)
Shias say that no part of earth is suitable for sajdah. If they offer salah in the mosque then they put a wooden tablet before them and do sajdah over it, and when they offer salah in forests then they do sajdah on the leaves of trees. This is a false belief and it is against the holy Quran and Hadith. Their Fiqh Jafari is also fabricated. It is not lawful to use that pagdi. If you did sajdah over pagdi instead of ground then it shall make your salah makrooh.
