Purifying mosque carpets with chemical cleaners

A question on removing impurity from mosque carpets with liquid chemical cleaners, in which Egypt's Dar al-Ifta answered that this suffices and water is not required. ¹

The questioner asked whether purity is achieved when impurity on a mosque carpet is removed with modern liquid chemical cleaners, or whether only water will do. ¹

Dar al-Ifta answered that purifying the place of impurity is not limited to water, but is achieved by any pure liquid that removes it. ¹ It said these cleaners are in principle pure in themselves and remove the substance of impurity, as specialists state and experience shows, so carpets may be purified with them. ¹ It relied on the rule that things are pure in principle, citing al-Hattab's commentary on the Mukhtasar of Khalil and Ibn Hajar al-Haytami's Tuhfat al-Muhtaj. ¹

Egypt's Dar al-Ifta published this fatwa on its site as no. 9018, dated 27 July 2026, among the fatwas of Grand Mufti Nazir Ayyad. ¹ The museum records this text as a historical document attributed to the body or scholar that issued it; it issues no ruling of its own.
