需要去除污秽的对象有三类,学者们对此存在分歧。第一是身体,其次是衣物,最后是清真寺和礼拜场所。法学家们在这三类对象上达成了一致,因为它们在《古兰经》和圣训中有明确的提及。

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.

关于衣物，经文中有至高者的话语：“你要洁净你的衣服”，这是按照那些作字面理解者的解释而言的；还有先知（愿主的赞颂与平安降临于他）关于洗去衣服上的经血的命令，以及关于在孩子在他膝上小便之处浇水的命令。清真寺也属于这一规定的范围，先知（愿主的赞颂与平安降临于他）曾命令往清真寺角落里那位乡下人小便之处浇上一桶水。同样，从先知（愿主的赞颂与平安降临于他）处亦有确证：他“命令洗去身体受污处的前列腺液（madhy），并洗去两个出口上的污物”。

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”.

教法学者们对于因未同房前分泌的前列腺液（madhy）而是否需要清洗整个阴茎存在分歧。这一分歧基于广为流传的阿里的圣训，即先知（愿真主的赞颂与平安降临于他）被问及前列腺液时，他说："他应当清洗阴茎并进行小净。"分歧的原因在于，这一义务是针对整个受影响的对象，还是仅针对其中实际受影响的部分。主张这一义务适用于整体的人，即适用于该词所指的整个对象的人，认为应当清洗整个阴茎；而主张这一义务适用于该对象的最低必要部分的人，则以类比小便为据，认为只需清洗受影响的部分。

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.
