Namoz dastlab va umuman olganda ikki turga bo‘linadi: farz va sunnat (mustahab). Ushbu ibodatning asoslariga oid bahs to‘rt toifa, ya’ni to‘rt qismga cheklanadi. Birinchi qism farzning belgilanishi va unga bog‘liq masalalar haqida. Ikkinchi qism uning uch shartini belgilash haqida: vujub sharti, sihhat sharti va kamolot sharti. Uchinchi qism uning amal va so‘zlarini, ya’ni uning rukunlarini belgilashni o‘z ichiga oladi. To‘rtinchi qism uning kechiktirib ado etilishi va tartibsizlikdan keyingi tuzatish shakllarini belgilash haqida, chunki amalni kechiktirib ado etish, agar u to‘g‘ri bajarilganda bekor bo‘lmagan bo‘lardi.

Prayer is divided initially, and as a whole, into two kinds: obligatory and recommended. The discussion covering the principles of this form of worship is confined to four categories, that is, four parts. Part One is about the identification of the obligation and matters related to it. Part Two is about the identification of its three conditions: the condition of obligation, condition of validity, and the condition of completion. Part Three covers the identification of its acts and words, and these are its essential elements (arkan). Part Four is about its delayed performance and the identification of forms of rectification following irregularity, for it is the delayed performance of an act that would not be deemed as lapsed had it been duly performed.
