عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كُنْتُ أُرَجِّلُ رَأْسَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَنَا حَائِض
Translation

Abu Huraira reported the Prophet as saying, “Jews and Christians do not dye [their beards], so act differently from them.” (Bukhari and Muslim.)

The Prohibition of Imitating Non-Muslims

This hadith from Mishkat al-Masabih (4423) establishes a fundamental Islamic principle: maintaining distinct religious identity. The command to dye beards serves as a practical manifestation of this principle, creating visible differentiation between Muslims and the People of the Book.

Scholarly Commentary on Beard Dyeing

Classical scholars emphasize that using henna or other natural dyes for beards is recommended (mustahabb), particularly for concealing white hair. This practice embodies the Prophetic guidance of maintaining a vigorous appearance while adhering to Islamic identity markers.

Imam An-Nawawi explains in his commentary on Sahih Muslim that black dye may be used, though many scholars prefer colors like henna (reddish-brown) to avoid deception or imitation of youth in advanced age.

Theological Significance of Differentiation

This injunction extends beyond mere appearance to encompass the preservation of Islamic distinctiveness in beliefs, worship practices, and moral conduct. Scholars like Ibn Taymiyyah note that imitation in external matters often leads to similarity in internal beliefs and customs.

The prohibition against resembling non-Muslims applies particularly in matters specific to their religious practices, ensuring Muslims maintain their unique spiritual identity while engaging in worldly affairs.

Contemporary Application

Modern scholars apply this principle to various aspects of life where Muslims might unconsciously adopt distinctive non-Muslim practices. The core principle remains: Muslims should maintain visible markers of their faith identity while avoiding practices uniquely associated with other religions.
