Nowadays, some of the things that are ḥarāmto be consumed, such as lard, its derivatives and alcohol are used as additives or additional nutrients in products, namely food and cosmetics that people use widely in daily life. The provision of these products, which are accepted as najis(impure), stands in front of us as one of the actual fiqh problems. In order to produce an accurate solution in this regard, the reaction condition and the level of dissolution in the product must (...) be determined. In this article, the level of mutanajjis (contamination) of the products that najisthings transforms through istihlāk(physical change) and the provision (hukm) of benefits from such things are examined. The research covers the discussions in the classical period regarding the provision of things, which included najāsah(impurity) and underwent physical change as well as the evaluations of contemporary Islamic jurists. The aim of this study is to contribute to the researches, which will be carried out to determine the provision of products containing ḥarāmelements. As the production is carried out on an industrial scale, such studies are important today in terms of the establishment of “ḥalāl” sensitivity and meeting the needs of people who have this sensitivity to learn the provision of such products.SummaryNowadays, in various sectors, especially food, feed, cosmetics, health and clothing industries, for the purposes of reducing the cost of the product, extending the shelf life, making the product more attractive in terms of color, consistency and aroma, many substances are added to the main material. The fact that some of the substances added are ḥarām(forbidden) such as blood, lard, pest, and ethyl alcohol require the subject to be considered in terms of fiqh. It is important to clarify two issues in order to reach a healthy result in the studies aiming to determine the provision (ḥukm) of the products that are mixed with najis(impure) substance. One of them is the determination of the level of istihlāk(physical change) in the mutanajjis(contamination) things. The second is the determination of the basic principles to be used in determining the provision of the things which najāsahhas undergone the physical change in. In this study conducted within the scope of this purpose and method, the hadīthsrelated to two different issues that are directly related to the subject have been evaluated as the basic textual basis. These are narrations about the cleanliness and pollution status of the contaminated water, and about the availability of fats and oils, which the dead mouse is seen in. It is stated in the narrations about the condition of the water that najāsah involved in, the water will not be najisunless its smell, taste or color changes because of the falling najāsahin it. According to this hadith, which shows the change of description as a measure, the fuqahāʾ(jurists) came to a consensus on the fact that water, which one of its characteristics changed because of najāsahwould be considered mutanajjis. When thishadithis evaluated together with the narrations that indicate the small amount of water is contaminated because of najāsah, in fact, it is seen that while the water is considered to be clean-najis, the situation of the water being affected from najāsahis taken as the basis and aimed to protect human health against the dirty water. At the time when there were not any one of today's microbiological analysis laboratories, the way to understand the pollution status of water was to see if the smell, color and taste of the water changed while taking the amount of the water into account. Since the rate of foreign matter in the water, the level of pollution and the health status of the water can be determined correctly in the laboratory today, operating the modern techniques as well as the measure of qualification change will be appropriate for the purpose of the hadīthsmentioned.In the narrations about the state of the fat, which the dead mouse is found in, it is seen that different operations are requested depending on the fat being solid or liquid. If the fat is liquid, different instructions have been made such as its being poured or used in lighting. Mālikīs, Shāfiʿīs, and Ḥanbalīfaqīhs (jurists) of the first period have ruled that liquids such as vinegar, milk and honey are mutanajjis, whether they are in little quantity or not, and whether their descriptions are changed or not, claiming that the amount of oil and the degree of impact on the dirt is not declared in the hadīths. The Ḥanafīs adopted the provision in the narrations mentioned pointing to a small amount of liquid oil and considered the measure of description change for a large amount of liquid valid. Ẓāhirīs, Ibn Taymiyyah and some of the faqīhsargued that the liquids which one cannot feel the color, taste or smell of the najāsahin are clean, regardless of the amount.These three approaches are open to criticism because the first is limited only to the literal meaning in the narrations and neglects the aims, and the second ignored the non-water fluids’ ability to hide the descriptions of the substance added to them, and the third evaluates the mustahlak substance (that has undergone a physical change) as if it had been istiḥālah(chemically changed). When the narrations related to the subject are examined, it is understood that while the usage of the liquid fat which the dead mouse was seen in as the food was prohibited, in fact, it was based on the foresight that all of the fat is affected by the mouse. It appears to have been ruled out that only the part polluted is the part affected by thenajāsahfor the fact that after the removal of the mouse and the environment from the solid oil exposed to the same contamination, the rest is allowed to be eaten. According to this, it is possible to say that the measure of mutanajjisin the things that affected by najāsahis in the degree of spreading of najāsah.Nowadays it is possible to determine the presence of najisthings in the main material, which is used as additive or addition, by the level of effect of these substances in the product, as well as by the assays. If the najissubstances used for purposes such as brightness, taste, consistency and extending shelf life, perform the expected functions, it means that they protect their presence in the product effectively. In fact, it should be acknowledged that these substances continue to exist effectively in the product, if they perform the targeted function without any chemical change, even the ratio in the product is low or the color, taste and odor are eliminated during the mixture.The faqīhswhile differed in opinion about the mutanajjisof things that the najāsahhad undergone physical changes in, they, in concert, considered the substances, which were not cleaned or could not be cleansed from which that they accept as mutanajjisby their own measurements, khabīs(disgusting), and have accepted the people’s eating of them as ḥarām. Likewise, they did not allow such things to be used in any way touching the body, clothing and containers. They have evaluated the narrations, which requires the spilth the fat that the dead mouse was seen in, as the main basis in this issue. On the other hand, about the use of the mutanajjisthings outside the human consumption area and in such a way that the clothes and body would not be contaminated; the majority of thefaqīhs preferred the mubāḥ provision. They have put forth the narrations as the basis that recommends the usage of the liquid oil in which the mouse was fallen in lighting. These approaches of the fuqahāʾabout the effect of the istihlākon the provision of making use of the things that affected by najāsahare of worth as the basic principles on the subject. It is possible to say that it is not permissible to consume food products containing lard or pork gelatin, and the chicken that has been torn apart while being left in hot water in order to pluck its feathers, and the egg which becomes mutanajjisfor it is boiled up with thenajāsahon, and the using of cosmetic products containing lard when today’s industrial products are evaluated in accordance with these principles. If taken the general opinion that defends that the ethyl alcohol is najis as the basis, the carbonated soft drinks, which are added to alcohol, can also be evaluated in this context. (shrink)

The lack of water, which has arisen due to reasons such as climate change, excessive and misuse, has become a global problem. The reuse of wastewater is considered as an important solution to overcome this problem. With the technology developed for this purpose, wastewater is treated and used in many fields, especially in irrigation of agricultural products and parks and fire extinguishing. There is no information directly related to the methods of treating polluted water in the religious texts. In the (...) past, when today's technological possibilities were not available, fuqaha determined some treatment techniques, but these are about waters exposed to najāsat (filthy things), not about wastewater that contains a large amount of najis elements. As a matter of fact, it seems impossible to clean wastewater with these methods. With the systems developed today, wastewater can be treated at different levels according to their usage areas. Accordingly, the analysis information regarding the output at each treatment level should be evaluated separately when determining the fiqh provision of treated wastewater. In this study, it is aimed to examine the purification methods discussed in fiqh books together with the relevant texts and to determine the criteria taken as basis in purification and to try to determine the fiqh provision regarding the treated wastewater outputs within these criteria.
