fields of study—medicine, engineering, military science, and pharmacy—were among the most highly competitive and prestigious disciplines in the university system. The rank-and- file members of Islamist groups have come from the middle class, the lower-middle class, and the urban working class. Various Islamist groups espoused different means for achieving their political agenda. All Islamists, however, were concerned with Islam's role in the complex and changing society of Egypt in the late twentieth century. A common focus of their political efforts has been to incorporate the Shari'a into the country's legal code. In deference to their increasing influence, the Ministry of Justice in 1977 published a draft law making apostasy by a Muslim a capital offense and proposing traditional Islamic punishments for crimes, such as stoning for adultery and amputation of a hand for theft. In 1980 Egypt supported a referendum that proposed a constitutional amendment to make the Shari'a "the sole source of law." The influence of the Islamists temporarily waned in the aftermath of Sadat's assassination in 1981, but the election of nine members of the Muslim Brotherhood to the People's Assembly in 1984 revived Islamists' prospects. In 1985 the People's Assembly voted to initiate a procedure for the gradual application of the Shari'a, beginning with an indefinite education period to prepare the population for the legal changes; the next step would be to amend all existing laws to exclude any provisions that conflict with the Shari'a. Moves to reform the legal code received support from many Muslims who wanted to purify society and reject Western legal codes forced on Egypt in the 19th and 20th centuries. As of 2009, the Grand Mufti also has another title, Dar al-Iftaa, a part of the Ministry of Justice. While his rulings are nonbinding, they are "influential." His office issues 5,000 fatwas a week. By the beginning of the 21st century, only the Gama'at Islamiya leaders who were in prison after the assassination of Sadat were released after several books they wrote and interviews showed that they revised their points of view and changed the radical tone of their speeches. Status of religious freedom The Constitution provides for freedom of belief and the practice of religion; however, the Government places restrictions on this right. According to the Constitution, Islam is the official state religion, and Shari'a is the primary source of legislation; religious practices that conflict with the official interpretation of Shari'a
