Taharah: Purification and Its Conditions

The chapter on taharah (ritual purification) in Fath al-Qadir follows the structure established by Al-Hidayah, beginning with the fundamental principle that purification is a prerequisite for valid prayer and certain other acts of worship. Ibn al-Humam's treatment is notable for its depth of evidential engagement and its willingness to examine the chains of hadith transmission that underpin each ruling.

In the Hanafi school, water is categorized into several types for purposes of purification. Pure water (ma' mutlaq) — unrestricted water, meaning water that retains its natural description — is the valid medium for wudu and ghusl. This includes rainwater, river water, seawater, well water, and water from melting snow or ice. The Quran commands believers to purify themselves with pure water (Surah al-Ma'idah 5:6), and the Prophet confirmed the purity of seawater in a well-known hadith.

Fath al-Qadir gives particular attention to the question of water that has been used (musta'mal water) — water that has fallen off the limbs after performing wudu or ghusl. The Hanafi position is that such water is pure in itself but does not remain a valid agent for purification; it cannot be used for a second act of wudu. Ibn al-Humam examines the evidential basis for this ruling, engaging with hadiths cited by other schools and explaining how the Hanafi position is derived from a combination of prophetic practice and juristic reasoning.

The discussion of najasah (ritual impurity) in Fath al-Qadir distinguishes between heavy impurity (najasah ghalizah) — including human waste, blood, wine, and the flesh of animals whose consumption is prohibited — and light impurity (najasah khafifah), such as urine of animals whose meat is permissible. The thresholds for these distinctions follow established Hanafi criteria, with the heavy impurity requiring removal down to a defined quantity before prayer becomes valid.

Ibn al-Humam's commentary on the chapter of wudu begins with the Quranic verse prescribing it and then examines each of the four obligatory acts (fard): washing the face, washing the arms to the elbows, wiping the head, and washing the feet to the ankles. He also covers the recommended acts (sunnah) and desirable acts (mustahabb) that accompany wudu, and the acts that invalidate it — including the emission of anything from the front or back passage, sleep, loss of consciousness, and flowing blood in sufficient quantity.

The ghusl (full ritual bath) section addresses its obligatory occasions: sexual intercourse, ejaculation, the ending of menstruation, and postnatal bleeding. Ibn al-Humam specifies the three fard elements of ghusl according to the Hanafi school: rinsing the mouth (madmadah), rinsing the nose (istinshaq), and washing the entire body including the hair. He contrasts this with the Shafi'i and Hanbali positions, which do not make the rinsing of the mouth and nose obligatory in ghusl, explaining the hadith evidence from both perspectives with characteristic scholarly balance.

The chapter on tayammum (dry ablution using earth or dust) appears when water is unavailable or its use would cause harm. Ibn al-Humam explains that tayammum is performed with two strikes against pure earth: one for the face and one for the arms to the elbows, wiping each fully. The ruling that tayammum is invalidated by the availability of water — even mid-prayer — is a Hanafi position Ibn al-Humam explains with care, since it differs from the other schools.
