Islam has defined the way of constitution in the light of which the Islamic constitution is arranged. Based on this constitution, a state is considered Islamic or non-Islamic state. After the creation of Pakistan, Jamaat-e-Islami first paved the way for the resolution objectives. With the advice and consent of Syed Abul Alaa Maududi (R.A), a draft of the objectives of the resolution was prepared and approved by the Constituent Assembly on March 12, 1949. The purpose of the resolution was actually the word of the state that transformed it into an Islamic state. With the adoption of the Resolution's objectives, a Fundamental Principles Committee was formed, which submitted its constitutional report 19 months later. This report was rejected by Jamaat-e- Islami and public circles. In August 1952, Jamaat-e-Islami presented a detailed constitutional outline so that the report of proposed principles could be based on Islamic principles. However, the second report was also rejected. On October 7, 1953, the reconciliation formula was presented by the Prime Minister, but before its approval, the assembly was dissolved. With the newly formed Assembly, Jamaat-e-Islami's struggle was renewed once again. Finally, as a result of Jamaat-e-Islami's efforts and movement, the first Islamic constitution came into effect in the country of Pakistan on March 23, 1956.
