The IIFA's activities revolve around concluding researches and documentations as well as organizing events and meetings between Islamic scholars and experts in various fields of knowledge.

[5] The current president is Sheikh Dr. Salih bin Abdullah al Humaid, Imam of the Grand Mosque in Makkah.

Its Secretary-General is Prof. Koutoub Moustapha Sano, a former Minister of Religious Affairs in the Republic of Guinea, a recognized Islamic scholar and thinker.

This mission is based on a comprehensive and integrated understanding of the Islamic religion, its foundations, its sources, its objectives, its principles, and its provisions.

The Fiqh Academy aims at becoming the world's leading jurisprudential reference to which turn the countries of Islamic world and the Muslim communities in order to clarify the positions of Shariah on issues of concern to Muslims and to provide appropriate solutions to the problems of contemporary life, derived from the Holy Qur'an, the noble prophetic Sunnah and the rich Islamic heritage.

The IIFA took a firm stand against the coronavirus pandemic and was one of the first Islamic institutions to condemn the COVID-19 conspiracy theories and call for public preventive measures.

It refuted the irregular fatwas issued by individual muftis and unreliable organizations that doubted the COVID-19 treatment or called for public disobedience to preventive measures.

Instead, it urged the masses to rely on Islamic legal opinions from renowned scholars and physicians to deal with the COVID-19 pandemic.

[26][27] In June 2006 (Ramadan 1427 AH), under the auspices of the International Islamic Fiqh Academy, several dozen Iraqi religious leaders from Sunni and Shia factions took part in a two-day meeting[28] near Masjid al-Haram in Makkah and signed the Makkah Document that called to take practical steps to end the sectarian violence in post-Saddam Iraq.

The Makkah Document supposedly called for the formation of committees in various parts of Iraq and for organizing seminars of Sunni and Shia religious leaders and scholars.

Representatives are appointed by Member states from among the most eminent scholars in their countries, many of whom are current or former ministers, grand muftis, and university professors.
