Based on the viewpoint shared by Shiite jurisprudents, the second source of jurisprudence is ‘‘Sire’’. The Holy Prophet (PBUH) and Imams' (AS) words and deeds that are called ‘‘Sire’’ are considered as religious justification used as a reason for inferring from religious orders.

In order to infer from religious orders, jurisprudents refer to the Holy Prophet (PBUH) and Imams' (AS) practical Sire which aimed at explaining an issue or removing its ambiguity as an independently supportive reason to prove their claim.

The intention of investigating this subject was to gain an understanding of the Shiite jurisprudents' approach to dealing with the Holy Prophet (PBUH) and Imams' (AS) deeds as well as discovering the jurisprudents' position to their deeds, i.e. to find out if they deal with the deeds the same way as they deal with the words or not.

In this study, it was tried to investigate types of Shiite jurisprudents' reference to the practical Sire of the Holy Prophet (PBUH) and Imams (AS) and explain the viewpoints shared by the jurisprudents. Authentic sources of Islamic jurisprudence were benefitted from in this study.
