Haji Shariatullah (Bengali: হাজী শরীয়তুল্লাহ; 1781–1840) was a prominent religious leader and Islamic scholar from Bengal in the eastern subcontinent, who is best known as the founder of the Faraizi movement.

[2] Following this, Shariatullah then headed north to Murshidabad to meet with his uncle, Ashiq Miyan, who was working in the district as a court official.

During the first two years, Shariatullah stayed in the home of Mawlana Murad, a Bengali Muslim migrant who permanently resided in Makkah.

The second phase of his stay was the most notable and spanned over a 14-year time period in which Shariatullah studied under a prominent Hanafi jurist known as Tahir al-Sumbal Makki where he was introduced to tasawwuf and the Qadiriyya.

[6] According to James Wise and Hidayet Hosain, Shariatullah came back to Bengal from Arabia as a skilled scholar of Islam and Arabic.

[citation needed] Shariatullah's Faraizi movement focused on reforming the es of Bengali Muslims based on the Hanafi school of Islamic jurisprudence.

[1] The reaction of these landlords, both Muslim and Hindu, as well as European indigo planters, caused the movement to become a socio-economic issue.

[10] After the death of Haji Shariatullah in 1840, leadership of the Faraizi movement passed to his only son, Muhsinuddin Ahmad popularly known as Dudu Miyan.

[13] As of 2005, the 450 metres (1,480 ft) Haji Shariatullah Bridge over the Arial Khan River on the Mawa-Bhanga highway in Shibchar is named after him.

[14] A biography film was made in Bangladesh titled Haji Shariatullah directed by Hafizuddin and portrayed by Ilias Kanchan.
