He served as a chairman of the
Iraqi National Party in 1922. He served as Minister of Commerce in the second cabinet of
Abd al-Rahman al-Gillani. Also in 1935, at-Timman agreed to the plan of
Hikmat Sulayman, who came to the belief that al-Ahali Party should forcibly overthrow the government of Yasin al-Hashimi and then reform Iraq from above, following the example of
Kemal Atatürk's reforms. He supported
Bakr Sidqi's
military coup in 1936 and served as
Minister of Finance in the cabinet of Hikmat Sulayman from 29 October 1936 until he resigned in June 1937. But then al-Timman's hopes for a deep reform of the country did not come true. He was disappointed by the attitude of Hikmat Sulaiman, who very quickly began to strive for more authority in power. Already in 1937, al-Timman and
Kamil al-Chadirji left the government, protesting against the attitude of the prime minister, who resigned from the reforms previously demanded by al-Ahali. Additionally, al-Timman was outraged by the fact that Sulayman and Bakr Sidqi brutally suppressed the uprising of the Iraqi Shi'i Muslims. == Death ==
