Does the Shia practice of Sajdah on clay or any earthly material include placing the palms, knees, and feet on clay as well, as the Prophet did? If not, why is this practice restricted to prostration of the forehead?

The Prophet Muhammad (SAWA) never placed his forehead in Sajda but on clay or a material from the clay. He said: ( Earth is a place of my prostration and source of purification جُعِلَت لي الأرضُ مسجدا وطَهورا . This Hadeeth is narrated in Sunni books including Saheeh Al-Bukhari.

Placing palms, knees and feet must be on Taahir (pure) item but not necessarily on clay. This is according to authentic Hadeeths from the Prophet (SAWA). Details of these Hadeeths are mentioned in our jurisprudence books like Jawahir  Al-Kalaam and our Hadeeth books like Wasaa'il Al-Shia by Al-Hurr Al-Aamily.
