Architects: Vedat Dalokay Faisal Masjid, Islamabad. Construction began in 1984 and it was opened for worship in 1986. It is one of the largest mosques in Islamabad, with space for 20,000 people. The mosque is named after its founder who was an Islamic scholar and teacher. He had been living in London when he died in 1983 at the age of 44. He left no children and so his entire estate, including money and real estate, was given to charity. The mosque was built using funds from his charity. It took seven years to complete and costs about $750,000 (1980 dollars). Faisal's father, Al Haj Muhammad Ahmad, founded the Jamaat-e-Islami movement in 1952. His mother was a sister of Ghazi Muhammad, another leader of the movement. Both of them were from a very wealthy family and they used their wealth to spread Islam. They traveled around Pakistan preaching about Islam and building schools and hospitals. When Faisal was only five years old, he led a prayer ceremony at their home.
