According to Imāmī doctrine, the ability to perform miracles (Mugizāt) is one of the characteristics of the Imām. This goes against the position of the Sunna, which claims that only prophets are able to perform miracles. The article discusses the various definitions of miracles in Islam and surveys the miracles attributed to Imām Gafar al-Sādiq (d. 148/765). This survey demonstrates the various capabilities attributed to the Im m and illuminates a number of patterns common to the traditions relating the Im m's miraculous deeds. The most noteworthy of these patterns is the association of a miracle performed by the Imāmī with a qurānic miracle, usually performed by a prophet. The aim of this pattern is to reinforce the Imāmī position regarding the equal status of an Imāmī and prophetic miracle.
