The prayer soil or Torbat is a piece of stone or soil molded on which the Shiites put their foreheads on prostration. Although prostrations are not necessary from the Shiites' point of view and can prostrate on earth, soil, stone and what you go from the earth (other than food and clothing), the Shiites use the soil as one of the prophets. Akram and their Ahlul -Bayt know prostrate in the use of soil, stone and land.
According to Shiite jurisprudents, prostration to Torbat Imam Hussein (AS) is obligatory. They prostrate and prostrate from this Torbat. Wahhabis consider making and prostrating over the seal; But the Shiites believe the seal is the same soil.
Can you pray without a stamp?
Seal is not obligatory. What is obligatory is prostration to the ground. If you pray on soil, stone, mat, wood, tree and paper, it's okay.
But according to the traditions we have of Prophet Muhammad (peace be upon him) and the Imams (PBUH), prostration to the carpet and fruits is false. The reason is that the Prophet (peace and blessings be upon him) said:
God has placed the earth for me, the prostrate and the place of purity.
جعلت لی الأرض مسجدا و طهورا.
