Taharah in Al-Muhadhdhab: Al-Shirazi's Analysis

Al-Shirazi's treatment of taharah in Al-Muhadhdhab follows the Shafi'i school's systematic approach to purification, presenting rulings with their evidential basis and comparing them to the positions of other schools. His analysis laid the groundwork that Al-Nawawi would later build upon extensively in Al-Majmu.

The chapter opens with the classification of water — a topic al-Shirazi treats with careful reference to the hadith of the two qullahs (Abu Dawud) and the broader principles of Shafi'i jurisprudence regarding when water is rendered incapable of purification. He explains that any water below two qullahs that comes into contact with an impurity — regardless of whether the water changes — is rendered impure and incapable of purifying. Water at or above two qullahs is only rendered impure if one of its three characteristics (color, smell, or taste) actually changes.

Al-Shirazi then turns to the question of impurity types (najasah) and their purification. He distinguishes the three tiers of Shafi'i impurity classification and gives particular attention to the mughallazah (heavy) impurity from dogs. He explains the sevenfold washing requirement with earth based on the hadith in Sahih Muslim, noting that the 'earth' requirement is interpreted by the Shafi'i school to mean any cleansing agent that functions like earth — including soap and similar substances. This practical interpretation of the rule is an example of al-Shirazi's attention to the goals behind legal rulings.

On wudu, al-Shirazi's treatment in Al-Muhadhdhab covers the six obligatory acts of the Shafi'i school: intention, washing the face (which includes the mouth and nose as part of the face — though the rinsing of mouth and nose in wudu is classified differently from the Hanbali school), washing the arms, wiping part of the head, washing the feet, and performing the acts in order. He defends the Shafi'i requirement of order (tartib) against the Maliki school's view that order is not obligatory, explaining the reasoning based on the Quranic verse's sequencing and the Prophet's consistent practice.

Al-Shirazi gives special attention to the question of what constitutes the face (wajh) for purposes of wudu. The face is the area from the top of the forehead to the bottom of the chin and from earlobe to earlobe. The beard of a man — if it is thick enough that the skin beneath cannot be seen — does not need to have water reach the skin; washing the outer surface of the beard is sufficient. If the beard is thin enough to see through, the skin must be reached. This analysis reflects the Shafi'i school's careful definition of the anatomical boundaries of each washing obligation.

On the invalidators of wudu, al-Shirazi covers the touching-women question with characteristic care: the Shafi'i school holds that skin-to-skin contact with a non-mahram member of the opposite sex breaks wudu, based on the Quranic phrase 'or you have touched women.' He acknowledges that the Hanafi school interprets this phrase as referring to sexual intercourse (a meaning supported by the Arabic idiom of the time), not mere touching, and presents both sides of the argument. His treatment of this disputed question exemplifies the comparative approach that makes Al-Muhadhdhab valuable beyond the Shafi'i school.

Al-Shirazi's ghusl chapter follows the same pattern: precise statement of the Shafi'i obligatory elements, evidence for each, comparison with other schools, and address of edge cases (ghusl with contaminated water when pure water is unavailable, ghusl with sea water, the validity of a single combined ghusl and wudu).
