Sir Syed Muhammad Saadulla KCIE (Assamese: ছাৰ ছৈয়দ মহম্মদ ছাদুল্লাহ; 21 May 1885 – 8 January 1955) was the 1st Prime Minister of Assam in British India from 1937 to 1946.

Preoccupation with legal profession and civic responsibilities and duties of a Legislative Councillor left Saadulla with little time for recreation.

Most afternoons he played Lawn tennis at the erstwhile Jubilee Gardens, where the regulars were Tarun Ram Phukan, Gopinath Bordoloi and Hemanta Kumar Lahiri.

With his enhanced fortunes Saadulla bought a plot of land adjacent to his father's house, and built a large residence for the joint family and an outhouse to serve as his office.

He consulted his younger brother, Syed Muhibulla, a Professor of Arabic and Persian at Cotton College, Guwahati and asked for the blessings of his 80-year-old father, and prepared to leave for Calcutta.

Before long, briefs from Assam for appeal before the High Court began to arrive and once more Saadulla was engrossed in preparing plaints.

Towards the end of February, 1924 Saadulla received a letter from Sir Kerr, Governor of Assam offering him a seat in his Council.

As the newly elected Legislative Council was due to meet at Shillong on 24 March, there was very little time to decide between Calcutta High Court Bar and Ministership in Assam.

Saadulla wrote to the Governor accepting his offer and assuring him of reaching Shillong well in advance of the date of commencement of the Council session.

Opportunity was at hand, Sir John Anderson, Governor of Bengal, had personally offered him a High Court Judgeship.

Much to his dismay, Sir Harold Darbyshire, the Chief Justice, pointed out that he could not be appointed as a Judge for want of requisite experience of ten years of continuous practice at the Bar.

[4] As Assam premier, Saadulla also undertook land settlement policy to populate the state with migrants from erstwhile East Bengal.

Saadulla remained a close friend and associate of the Punjab Premier/Chief Minister Sir Sikandar Hayat Khan (in power from 1937 to 1942) and was a member of the executive committee of the All India Muslim League which met in March 1940 to draft the Lahore or Pakistan Resolution.
