Ijma is the consensus of the Muslim community on a point of law. It is one of the four sources of Islamic law, along with the Quran, Sunnah, and Qiyas.

Ijma must be unanimous in order to be valid. This means that all of the members of the Muslim community must agree on the point of law in question.

There are three main types of Ijma: Ijma al-sahaba (the consensus of the Companions of the Prophet), Ijma al-tabi'un (the consensus of the Followers of the Companions), and Ijma al-umma (the consensus of the entire Muslim community).

Ijma is one of the four sources of Islamic law, along with the Quran, Sunnah, and Qiyas. It is used to supplement the Quran and Sunnah, and to interpret their meaning.

Ijma cannot be used to change a ruling of the Quran or Sunnah. It can only be used to supplement the Quran and Sunnah, and to interpret their meaning.

There are many examples of Ijma in Muslim law. Some of the most well-known examples include the consensus that the five daily prayers are obligatory, the consensus that the month of Ramadan is a time of fasting, and the consensus that the pilgrimage to Mecca is a duty for all Muslims.

Ijma is of equal importance to the Quran and Sunnah. It is one of the four sources of Islamic law, and it is used to supplement the Quran and Sunnah, and to interpret their meaning.

There are a number of criticisms of Ijma. Some critics argue that it is too subjective, and that it is too easily manipulated by those in power. Others argue that it is not always unanimous, and that it can therefore be difficult to determine what the consensus actually is.

The criticisms of Ijma can be addressed by developing a more objective method for determining consensus, by making it more difficult for those in power to manipulate Ijma, and by encouraging greater participation in the process of Ijma.

Ijma is likely to continue to be an important source of Islamic law for the foreseeable future. It is a well-established tradition, and it is supported by a large body of scholarship. However, it is possible that Ijma will become less important as other sources of Islamic law, such as the Quran and Sunnah, become more widely accepted.
