Introduction

In Twelver Shi’a Islam, the rules governing the material used for prostration are explained primarily through narrations attributed to the Prophet Muhammad (peace be upon him and his family) and the Imams of the Ahl al-Bayt.

These narrations are central to the Shi’a understanding that the forehead should ordinarily be placed on the earth or on certain natural materials derived from it. The use of a clay tablet during prayer is one practical application of this jurisprudential principle.

1. The Earth as a Place of Prostration

A well-known prophetic narration states:

«“The earth has been made for me a place of prostration and a means of purification.”»

Arabic: جُعِلَتْ لِيَ الْأَرْضُ مَسْجِدًا وَطَهُورًا

Reference: Sahih al-Bukhari and Sahih Muslim, in their narrations concerning the distinctive features granted to the Prophet; related narrations are also transmitted in Shi’a hadith literature.

This narration establishes the earth’s suitability as a place of prostration and its role in purification. Shi’a scholars cite it alongside other narrations when discussing the permissibility of prostrating on the earth.

The narration does not, by itself, state that every Muslim must carry a clay tablet. Rather, it identifies the earth as a place on which prostration may be performed.

2. A Narration from Imam Ja‘far al-Sadiq

Hisham ibn al-Hakam asked Imam Ja‘far al-Sadiq about the materials on which prostration is permissible. The Imam is reported to have replied:

«“Prostration is not permissible except on the earth or on what grows from the earth, except that which is eaten or worn.”»

Arabic: السُّجُودُ لَا يَجُوزُ إِلَّا عَلَى الْأَرْضِ أَوْ عَلَى مَا أَنْبَتَتِ الْأَرْضُ إِلَّا مَا أُكِلَ أَوْ لُبِسَ

Reference: Shaykh al-Saduq, ‘Ilal al-Shara’i; related narrations are also recorded in Tahdhib al-Ahkam by Shaykh al-Tusi and Wasa’il al-Shi’a by al-Hurr al-‘Amili.

This narration is one of the principal reports cited in Shi’a jurisprudence regarding the surface used for prostration. According to its wording, the forehead may be placed on the earth or on qualifying materials that grow from it, with exceptions for materials commonly eaten or worn.

A small clay tablet is one practical way to ensure that the forehead rests on an appropriate surface, particularly when prayer is performed on a carpet or another textile floor covering.

3. The Wisdom Behind the Ruling

Explanations associated with this subject emphasize humility before God and avoiding the treatment of worldly possessions as objects of devotion.

The jurisprudential distinction is not that the earth possesses divine power. Rather, the material used for prostration must meet the conditions established by the relevant religious teachings.

A clay tablet is therefore not an object of worship. It serves as a suitable surface on which the worshipper places the forehead while worshipping God alone.

4. The Relationship Between Hadith and Jurisprudence

In Shi’a Islam, hadith are examined and interpreted by religious scholars according to principles of transmission, authenticity, context, and legal reasoning. A narration’s presence in a book does not automatically mean that every scholar considers its chain of transmission equally reliable.

The practical ruling concerning prostration is therefore based on the broader body of narrations and the jurisprudential conclusions drawn from them, rather than on one quotation considered in isolation.

Conclusion

Narrations attributed to the Prophet Muhammad and Imam Ja‘far al-Sadiq form an important foundation for the Shi’a rules concerning prostration. They explain why the earth and certain natural materials are regarded as suitable surfaces for sujood.

The use of a clay tablet is a practical application of these rules, not an act of worship directed toward the tablet itself.
