• The Shah Jahan Mosque was built in 1889 by Hungarian-British Orientalist Gottlieb Wilhelm Leitner. It was partly funded by Nawab Shah Jahan Begum of Bhopal, as a place for students at the Oriental Institute in Woking to worship. The Musjid was designed by architect William Isaac Chambers (1847–1924) and built in Bath and Bargate stone. It was designed in a late Mughal style, and has a dome, minarets, and a courtyard. The architecture was described by Pevsner Architectural Guides as “extraordinarily dignified”. The alignment with Makkah was established by a ship’s captain, brought in to take bearings.

• The Oriental Institute, for the students of which the Musjid was constructed, was founded by Leitner in 1881. He had purchased the former Royal Dramatic College building in Woking and established the Institute in order to promote oriental literature. It awarded degrees from the University of the Punjab in Lahore, Pakistan.

1889-1912 – Sunni period
The Musjid became the first formal place of Islamic worship in England. Queen Victoria’s British Indian employees and her British Indian secretary, Abdul Karim, used the Musjid when the Queen visited Windsor Castle. A small number of dignitaries, students, and guests used the Musjid until Leitner’s death in 1899, following which the Musjid closed.

During his 1895 visit of England, Afghan prince Nasrullah Khan prayed Eid al-Adha prayers at the Musjid and made a donation of £492 on the behalf of his father Emir Abdur Rahman.

1912-1935 – Lahore Qadiani/Ahmadi period
The Musjid fell into disuse between Leitner’s death and 1913. The London Mosque fund (which was founded in 1910) created the Woking Mosque Trust on Wednesday 17 April 1912. During that meeting it was agreed by all members that they were to take over the title deeds. It was also unanimously agreed by the committee members that Leitner’s son should be elected to the Woking mosque trust committee. The Woking Mosque, the Memorial House and related property was passed into the ownership of the Woking Mosque Trust by a document of Indenture dated 12 April 1915

Khwaja Kamal-ud-Din’s son Khwaja Nazir Ahmad gave credit to Mirza Abbas Ali Baig for saving the Musjid from being sold by the Leitner family for the purposes of a private factory.

“It is, however, with his services to the cause of Islam that we of the Woking Muslim Mission are chiefly concerned. It was Sir Abbas Ali Baig who saved from the hands of the Leitner family the Shah Jehan Mosque and Sir Salar Jung Memorial House at Woking and thus rescued them from the fate of being converted into a private factory. He subsequently founded the Woking Mosque Trust and raised funds for its maintenance.”

Khwaja Kamal-ud-Din, a prominent Kashmiri lawyer was invited to become the Imam and help maintain the mosque. It attracted royal visitors and famous British converts, such as Lord Headley and Marmaduke Pickthall. During the First World War, the incumbent imam, Sadr-Ud-Din, petitioned the UK government to grant nearby land to the Musjid as a burial ground for British Indian Muslim soldiers. By 1917, this burial ground, designed by T Herbert Winney and now Grade II listed, had been constructed and received the bodies of 19 soldiers from the hospital for British Indian soldiers at Brighton Pavilion.

On 28 May 1922, the Musjid held a celebration of Eid al-Fitr at the end of Ramadan, thought to have been the first time such public celebration had taken place in the United Kingdom. It was at this celebration that Kamal-ud-Din announced that the Musjid would be named Shah Jehan, after its benefactress.

Until the arrival of Pakistani immigrants in the UK in the 1960s, the Shah Jahan Mosque was the centre of Islam in Britain. It was from the Musjid that The Islamic Review was published, as well as Maulana Muhammad Ali’s popular English translations of the Quran. It has also been claimed as the location at which the name ‘Pakistan’ was coined. Among those that visited the Musjid in this time were Faisal of Saudi Arabia, Muhammad Ali Jinnah, Haile Selassie, Mir Yousuf Ali Khan, Aga Khan III, and Tunku Abdul Rahman.

1935-present – Sunni period
Khwaja Kamal-ud-Din died in 1932, and in 1935, due to increasing pressure from Sunnis, the Musjid officially broke ties with Ahmadi movement and returned to being a Sunni Musjid. It was badly damaged in June 2016, after floods swamped homes in the surrounding area,
