Hussein was born into a Hadame family (part of the larger Rahanweyn clan), in the central town of Xuddur in the Bakool region.
He studied, as was customary in those days in Somalia, the Qur'an, learning and memorizing entire chapters of the Muslim holy book. He later supplemented his studies in Islamic history.
Hussein became a businessman in his early adult years, opening a store in Xuddur and later expanding to open a larger one in Baidoa, before he entered politics.
In the late 1940s, Hussein joined the then burgeoning, nationalist party of the Somali Youth Club (which later changed its name to the Somali Youth League). He served the SYL's head office in what was then known as Upper Jubba, which included several current regions of Southwestern Somalia.
He eventually rose to be a prominent member of the League and in 1956, he was elected to what was then the first national assembly of the Somali people, the Legislative Assembly, under the trusteeship of Italy. He was among the first formed, but limited government of the then prime minister of Abdullahi Issa. He at first served as deputy of justice minister and then as minister of justice.
Hussein was re-elected to the Legislative Assembly in 1959, just before the independence of the Somali state. He was a member of the newly reconstructed, from Legislative Assembly to Constituent Assembly, and was then re-elected in 1964.Hussein was the speaker of the Somali parliament, from 1965–1969, until the coup d'état that occurred in 1969. He briefly became President the week between the assassination of President Abdirashid Ali Shermarke and the day of the coup.
Along with prominent figures from the civilian government, Hussein was placed under house arrest by the new president of the republic, Mohamed Siad Barre; the first few years with severe restrictions which were later relaxed when he eventually reclaimed his freedom.
Hussein retired from politics in 1969 and devoted his time to his farm in Afgooye and studying Islam.
He died in Nairobi, Kenya in 2012 at the age of 100. He was accorded a state funeral by the government in Mogadishu, Somalia and was buried there on June 15, 2012.
Somalia today would've probably been better off if he became president.
