The Book of Adornment - Sunan an-Nasa'i 5097

"The Messenger of Allah [SAW] said: 'May Allah curse the woman who affixes hair extensions and the woman who has that done.'"

Commentary on the Prohibition

This hadith from Sunan an-Nasa'i addresses the practice of attaching artificial hair or hair extensions, known as "wasl" in Arabic. The severe wording - invoking Allah's curse - indicates the gravity of this prohibition in Islamic law.

Scholars explain that this prohibition serves multiple purposes: preserving natural creation as Allah designed it, preventing deception in marriage, avoiding imitation of immoral women, and maintaining modesty in adornment.

Scholarly Interpretation

Classical scholars including Imam an-Nawawi and Ibn Hajar al-Asqalani classified this prohibition under major sins due to the explicit curse mentioned. The curse applies to both parties - the one who performs the attachment and the one who requests it - emphasizing shared responsibility in sinful acts.

The prohibition extends to all forms of artificial hair attachment, whether using human hair, synthetic materials, or any substance meant to artificially lengthen or thicken natural hair.

Exceptions and Related Rulings

Scholars make exception for medical necessity, such as hair restoration after illness or treatment. However, mere cosmetic enhancement without valid medical reason remains prohibited.

This ruling is part of a broader Islamic ethic regarding personal adornment that emphasizes moderation, authenticity, and avoidance of practices that fundamentally alter Allah's creation without legitimate cause.
