Commentary on Nasal Cleansing
The command to clear the nose during ablution (wudu') serves multiple spiritual and physical purposes. From the perspective of ritual purity, the nasal passages may contain impurities that invalidate purification. The scholars of fiqh emphasize that water must reach the entire nasal cavity up to the soft part.
Medically, this practice promotes respiratory health by removing dust and impurities. Spiritually, it symbolizes the purification of one's sense of smell from encountering unlawful fragrances or unpleasant odors in prohibited places. The thoroughness in cleansing reflects the comprehensive nature of Islamic purification.
Wisdom of Odd Number in Istijmar
The instruction to use an odd number of stones during istinja' (cleansing after relieving oneself) contains profound wisdom. Odd numbers hold special significance in Islamic tradition, as evidenced by God's description of Himself as "the Odd" (al-Witr). This connects the mundane act of purification to divine attributes.
Practically, an odd number ensures thorough cleansing while preventing wastefulness. The minimum is three stones, with scholars recommending adding more in odd increments if necessary. This practice also trains Muslims in mindfulness, turning even the most private acts into occasions for remembering divine commandments and wisdom.
Legal Rulings and Implementation
The Hanafi school considers nasal cleansing (istinshaq) obligatory (wajib) in ablution, while other schools regard it as strongly recommended (sunnah mu'akkadah). Regarding stones, they must be pure, effective in cleansing, and not made of materials that are revered or otherwise unsuitable.
If stones are unavailable, water suffices, but the preference for odd numbers when using stones remains. This hadith demonstrates Islam's comprehensive guidance, covering both major acts of worship and personal hygiene, reflecting the religion's holistic approach to human life.
