The Prohibition of Imitating Non-Muslims in Religious Matters

The central legal argument of Iqtida' al-Sirat al-Mustaqim is that Muslims are prohibited from imitating the religious practices and cultural symbols of non-Muslims — specifically Jews, Christians, and in Ibn Taymiyyah's context, the Mongol-introduced practices of pagan origin. He builds this argument from multiple Quranic verses, hadith traditions, and the practice of the early Muslim community.

The Quranic Basis

Ibn Taymiyyah cites several Quranic passages that he reads as establishing the distinctiveness of the Muslim community. The command not to be among the polytheists (6:14), the instruction not to follow the desires of those who went astray (5:77), and the general Quranic narrative of how previous communities fell into error through deviation from their prophets' teachings — all are marshaled as evidence that Muslims must maintain vigilance against assimilation to non-Islamic patterns.

He gives particular attention to the hadith in which the Prophet commanded the Muslims to differ from the Jews and Christians in specific practices: starting prayer at a different time, breaking the fast at sunset rather than waiting for night, the distinctive call to prayer (adhan) rather than bells or horns. Ibn Taymiyyah treats these as instances of a general principle that the Muslim community's external distinctiveness is religiously significant — it is part of how the community embodies its testimony to God's unity and the validity of Islamic revelation.

Levels of Imitation: Kufr, Haraam, and Makruh

Ibn Taymiyyah does not treat all imitation of non-Muslims as equally prohibited. He distinguishes between imitation that constitutes disbelief (kufr) — such as performing the specific ritual acts of another religion with the belief that they bring one closer to God — imitation that is forbidden (haraam) but does not constitute disbelief — such as adopting religious celebrations that have no basis in Islam — and imitation that is merely disliked (makruh) — such as wearing distinctive clothing or hairstyles associated primarily with non-Muslim identity without any religious significance.

This graduated approach allows Ibn Taymiyyah to maintain a firm principled position against assimilation while acknowledging that not all cases are equally serious. The person who attends a Christmas celebration to strengthen social relationships without participating in the religious component is in a different moral situation from the person who performs a non-Islamic religious rite believing it to be Islamically meritorious.

The Application to His Own Era

The most immediate application of Ibn Taymiyyah's argument in his own era was to practices that had entered Muslim communities through contact with Mongol and Persian culture: celebrations of the Persian New Year (Nawruz), practices associated with astronomical traditions, and various ceremonies at graves that he attributed to Zoroastrian or Christian influence. He argued that these practices, having entered Muslim communities not from the Prophetic Sunnah but from neighboring non-Islamic cultures, were innovations that Muslims were obligated to abandon.

He is careful to note that practices common in Muslim communities may have two different origins: those that entered through cultural diffusion from non-Muslims (and which his argument targets) and those that developed within the Islamic tradition itself, even if not explicitly commanded by the Prophet (which his argument does not necessarily target). The distinction is not always easy to draw in practice, and Ibn Taymiyyah acknowledges the difficulty while maintaining that the principle of investigation — tracing practices to their origins — is religiously obligatory.
