伊斯兰学科（Al-thaqafah al-Islamiyyah）是指那些因伊斯兰教义（‘aqīdah，信仰体系）而产生研习需要的各门学问。这些学科有的本身就包含伊斯兰教义，并保障其纯正，例如神学（‘ilm al-Tawhīd，认主学）；有的则以伊斯兰教义为根基，例如教法学（fiqh）、经训注释学（tafsīr）和圣训学（hadīth）；还有的是理解源自伊斯兰教义的各项律例所必需的学问，例如阿拉伯语言学、圣训术语分类学（muṣṭalaḥ al-ḥadīth）和教法原理学（‘ilm al-uṣūl）。

The Islamic culture are the disciplines the study of which is occasioned by the Islamic ‘aqīdah (creed), whether these disciplines included the Islamic ‘aqīdah and what guarantees its purity such as theology (ilm al-Tawheed) or they are based on the Islamic ‘aqīdah such as fiqh (jurisprudence), tafsīr and hadīth or whatever became necessary for the comprehension of rules emanating from the Islamic ‘aqīdah such as the sciences of the Arabic language, terminological classification of hadīth (mustalah al-hadīth) and science of the foundations of jurisprudence (‘ilm al-usul).

伊斯兰文化的一切都可追溯至《古兰经》和圣训（逊奈）。伊斯兰文化的各个分支，正是通过对它们的理解、依据它们而获得的。它们（《古兰经》与圣训）本身也属于伊斯兰文化，因为伊斯兰信仰（阿格itedah）要求人们接受并遵守其中所提到的一切。《古兰经》被降示给穆罕默德ﷺ，使他向民众阐明其中的经义。安拉说：

All of the Islamic culture is referable to the Qur’ān and Sunnah. And it is from them and through their comprehension and according to them that all the branches of the Islamic culture have been acquired. They (the Quran and Sunnah) are also from the Islamic culture because the Islamic ‘aqīdah obliges the adoption and adherence to whatever has been mentioned in them. The Qur’ān was revealed to the Messenger  so that he clarified it to the people. Allah  said:
