Shaykh Muhammad ibn Salih al-'Uthaymeen explained that the Hijab is a religious obligation (wajib) for every believing woman. The purpose of this divine injunction is to preserve the modesty, dignity, and honor of women, and to protect society from the sources of temptation (fitnah).

The correct and obligatory Hijab, according to the Shaykh, is that which covers a woman's entire body, including her face and hands, in the presence of non-mahram men (men she can legally marry). This position is based on a comprehensive analysis of the scriptural evidences and is considered the most cautious and sound view, although some scholars have permitted the uncovering of the face and hands.

The Shaykh emphasizes that the Hijab is not merely a cultural tradition but a clear act of worship and obedience to Allah. The conditions for a proper Hijab, derived from the Qur'an and Sunnah, are that it must be thick and opaque (not see-through), loose-fitting (not revealing the shape of the body), and should not be an adornment in itself, nor should it resemble the clothing of men or disbelievers.

Failing to observe the Hijab as prescribed is considered a sin for which a woman is accountable to Allah. It is a form of displaying one's adornments, which is prohibited.
