Ushbu turdagi ibodatning (^ibadat) asosiy qoidalari haqida batafsil bayon besh bobda berilgan. 1-bob uning farzligining dalillari, kimga va qachon farz ekanligi haqida; 2-bob uning amallarini aniqlash haqida; 3-bob esa u bilan amalga oshiriladigan narsani, ya'ni suvni aniqlash haqida; 4-bob uni buzuvchi omillarni aniqlash haqida; 5-bob esa u bilan ado etilishi mumkin bo'lgan narsalarni aniqlash haqida.

A comprehensive discussion of the principles of this (type of) worship (^ibadd) is covered in five chapters. Chapter 1 relates to the evidence of its obligation— on whom it is obligatory and when; Chapter 2 is about the identification of its acts; Chapter 3 is about the identification of that with which it is performed, that is, water; Chapter 4 is about the identification of factors nullifying it; and Chapter 5 is about the identification of things with which it can be performed.

Fiqhshunoslar najosatni ikki turga bo'lishadi: haqiqiy (haqtqiya) va hukmiy (huquqiy yoki texnik). Hadas atamasi huquqiy yoki texnik najosatga qo'llaniladi, xabas esa haqiqiy najosatga. Hadas kichik bo'lishi mumkin, uni vudu' bilan tozalanadi, yoki katta bo'lishi mumkin (jinsiy nopoklik va hayz), uni esa g'usl bilan tozalanadi (g'usl). Xuddi shunday, haqiqiy najosat og'ir (mug'allaza) yoki yengil (muxaffafa) bo'lishi mumkin.

23 Impurity (najdsa) is divided by the jurists into two kinds: actual (haqtqiya) and technical or legal (hukmiya). The term hadath is applied to legal or technical impurity, while khatyth to actual impurity. Hadath may be minor, which is removed through ablution, or it may be major (sexual defilement and menstruation) and is removed through bathing (gAws/). Similarly, actual najdsa may be heavy (mughallaza) or light (mvkhaffafa).

24 Vuzu (wudu') atamasi ham kichik (sug'ra) taharat deb ataladi, ghusl atamasi esa katta (kubro) taharat deb ataladi.

24 The term wad# is also referred to as the minor (sughra) ablution, while the term ghusl is referred to as the major (kubrd) ablution.
