What is the Shari'ah's view on supporting a political party for worldly gain, is Islamic liberalism permissible, and what are the best books on Islamic political theory for beginners?

The ruling on supporting parties varies depending on their identity and goals. It is not permissible to support parties based on principles contrary to religion, such as communism and secularism. However, rulings may differ based on the specific circumstances of Muslim minorities, which necessitates consulting scholars. Islam and liberalism are separate methodologies that do not converge. As for the best books on Islamic political science for specialists, they include: Al-Madkhal ila Al-Siyasah Al-Shar'iyah (Introduction to Islamic Political Science) by Abd Al-Aal Ahmed Atwa, Adwa' ala Al-Siyasah Al-Shar'iyah (Lights on Islamic Political Science) by Saad Al-Otaibi, and Al-Nizam Al-Siyasi Al-Islami (The Islamic Political System) by Munir Al-Bayati. Beginners are not advised to study Islamic political science before studying fiqh (Islamic jurisprudence) and its principles.
