Najosatlar tozalanishi kerak bo'lgan narsalar uchtadir, ular haqida ixtilof bor. Birinchisi badan, keyin kiyim, va nihoyat masjidlar va ibodat joylari. Fuqaholar bu uch narsa haqida kelishib olganlar, chunki ular Kitob va sunnatda aniq zikr qilingan.

The objects from which impurities are to be removed are three, and there is dispute about them. First is the body, then clothes, and finally the mosques and the places of prayer. The jurists agreed about these three objects as they are expressly mentioned in the Book and the sunna.

Kiyimlar haqida Yuce Allohning so'zlarida shunday deyilgan: "Kiyimingni poklagin". Bu so'zni tafsir qilganlar, uni zohiriy ma'noda tushunganlarga ko'ra, va Payg'ambar (ﷺ)ning hayz qoni kiyimdan yuvib tashlanishi haqidagi buyruqlarida, shuningdek, o'z qo'ynida siydik qilgan go'dakning siydigi tegib qolgan joylariga suv quyish haqidagi buyruqlarida ham shunday. Masjidlar haqida esa, masjidning bir burchagiga siydik qilgan a'rob ustiga bir ko'za suv quyishni buyurgan Payg'ambar (ﷺ)ning hukmi bilan qoplanadi. Shunga o'xshash, Payg'ambardan (ﷺ) sobit bo'lganidek, u (ﷺ) "madiyni tanaga tegib qolgan joylaridan yuvishni va ikki yo'ldan chiqqan najosatlarni yuvib tashlashni buyurgan".

Clothes are mentioned in the words of the Exalted, “Thy raiment purify , according to those who interpreted this literally, and in the commands of the Prophet (God’s peace and blessings be upon him) about washing away the blood of menstruation from clothes and about pouring water over the parts affected by the urine of the child who urinated in his lap. The mosques are covered by the command of the Prophet (God’s peace and blessings be upon him) to pour a pitcher of water over the urine of the bedouin, who had urinated in a corner of the mosque. Similarly, it is established from the Prophet (God’s peace and blessings be upon him) that “he ordered the washing of madhy from the affected parts of the body and the washing away of impurities from the two outlets”.

Fuqahо lar madhiy (nikohdan oldingi prostata suyuqligi) tufayli butun jinsiy a'zoni yuvish kerak-kerak emasligi haqida ixtilof qilganlar. Bu Aliy ibn Abu Tolib (r.a.) ning Payg'ambar ﷺ dan rivoyat qilingan, u zot madhiy haqida so'ralganda aytgan, mashhur hadisga asoslanadi: "U o'z jinsiy a'zosini yuvsin va vudu qilsin". Ixtilofning sababi shundaki, bu majburiyat butun ta'sirlangan narsaga taalluqlimi yoki unning haqiqatan ta'sirlangan qismlariga taalluqlimi, degan savolga bog'liq. Majburiyat butun narsaga, ya'ni bu atama qo'llaniladigan butun ob'ektga taalluq qiladi, deb hisoblaganlar, butun jinsiy a'zoni yuvish kerak, deydilar. Majburiyat ob'ektning zaruriy eng kam qismiga taalluq qiladi, deb hisoblaganlar esa siydik chiqarishga qiyoslab, faqat ta'sirlangan qismni yuvish kerak, deydilar.

The jurists differed aboutwhether the entire penis is to be washed because of madhy (prostatic secretion prior to cohabitation). This is based on the widely known tradition of cAIi from the Prophet (God’s peace and blessings be upon him) when he was asked about prostatic fluid. He said, “He should wash his penis and perform ablution”. .The reason for the disagreement is whether the obligation relates to the entire affected object or to the actually affected parts of it. Those who maintained that it applies to the whole, that is, to the entire object to which the term is applied, said that the entire penis is to be washed, while those who maintained that it applies to the essential minimum part of the object said that only the affected part is to be washed on the analogy of urination.
