In 1948, Nokrashy Pasha became very concerned with the assertiveness and popularity of the Muslim Brotherhood. Rumours of a Brotherhood coup against the monarchy and government had appeared, and the Brotherhood had already been implicated in the killing of Nokrashy Pasha's predecessor. Shortly after these rumours first gained currency, the prime minister formally outlawed the Brotherhood in December 1948, and this led directly to his own assassination. In addition to the Brotherhood being officially declared an illegal organization, the assets of the Brotherhood were seized by the government and many Brotherhood members went to prison.
