أساليب الحافظ الزيلعي في نقد متون السنة من خلال نصب الراية

The methods of Al-Hafiz Al-Zaili in criticizing of text of the Sunnah as described in his book Nasbu Al-Raya in analyzing the hadiths of Hidayah. The science of criticism is well known science since the era of the Companions, and critics of the hadith of the honorable companions have played a very important role in the field of narration and carefully criticizing it. And by passage of the era of the Companions and beginning the era of the followers (tabieen), the criticism became more obvious depending on the growing need, especially after spreading of lie, and creation of fake hadith, which led the critics to further research and verification, for scrutiny between the narrations and then differentiation between the right and the weak. The imams and scholars of hadith from the era of the Companions till present continuously inheriting the approach of criticizing the narratives in succession of their predecessors, whether criticizing the narrators or the texts. I have seen that it is worthwhile to stand on the efforts and methods of one of the imams in his criticism of the hadiths and I have chosen the effort of Imam Hafiz al-Zaili through his book " Nasbu Al-Raya in analyzing the hadiths of Hidayah" to learn how he was using the standards traded among the scholars of Hadith for textual criticism of Sunnah. As the those denied the hadiths from orientalists and their followers and those who follow their example simply claim that the scholars of hadith did not criticize the Sunnah in true criticism and even if they have criticized the hadiths, their criticism was only concerning the narratives not the text, now it is clear through this article that the scholars of hadith did not leave the side of the text, but they criticized text as they criticized the attribution of the hadiths. They set solid rules, which remain scholarly proven and accurate forever. We will revolve in this article around the following topics: learning about Al Hafez Zaili and the science of criticism, methods of textual criticism according to Hafiz Zaili, by focusing on: Criticism of the hadiths for violating the explicit meaning of the Qur'an, or for contradicting the Sunnah, or for contradicting the explicit consensus, or for risking and exaggerating the promise or the warning of simple action, or lack thereof in books of hadith These are the most important rules sited by al-Hafiz al-Zaili, which he practiced and criticized the hadiths and distinguished them between the correct and the weak.

Residual Status and Air-Soil Exchange Fluxes of Persistent Organic Pollutants in the Environment of Punjab Province, Pakistan

Contamination of different environmental compartments through persistent organic pollutants (POPs) is one of the most impending threats globally. The present study aims to investigate the first systematic data on the levels, distribution, possible sources and air-soil exchange fluxes of persistent organic pollutants (POPs) including organochlorine pesticide (OCPs), polychlorinated biphenyl (PCBs), polybrominated diphenyl ether (PBDEs) and dechloran plus (DP) in the air, surface soil and sediment samples from agricultural and industrial areas of Punjab Province, Pakistan. The present study was conducted in the catchment area of River Ravi from Punjab Province which is the most populated province of Pakistan with a population >90 millions; approximately 56 % of the total population of the country. Surface soils and air samples were taken from ten (10) sampling stations in Punjab Province, while seven (7) sampling stations were selected on the River Ravi to collect surface sediments. Air concentrations of POPs were estimated by using the polyurethane foam passive air sampling (PUF-PAS) technique. Air–soil exchange of POPs was estimated by calculating the fugacities in soil and air samples. Concentrations of ΣOCPs and ΣPCBs were ranged from 121-705 pg m-3 and 35-389 pg m-3 for air samples, 24.6-248 ng g-1 and 6.7-45 ng g-1 for soils and 2.7 to 99 ng g-1 and 4.6 to 424 ng g-1 for sediments, respectively. DDTs and HCHs were dominant OCPs in all air, soils and sediments while among PCBs, tri-, tetra- and penta-CBs was frequently detected homologues. Comparison of OCPs and PCBs concentrations with available sediment guidelines indicated severe contamination of DDTs and PCBs in the study area. Different indicative ratios for organochlorine residues in both soils and sediments suggested current use, long range transport along with past application of these chemicals to the total burden. WHO-TEQ values of dioxin like Σ10PCBs for soil samples obtained were very high and met the limitations, recommended by the Canadian Council of Ministers of the Environment (CCME). Levels of ΣPBDEs and DPs ranged from 8.2-124.7 and 1.5-529 pg m-3 for air, 0.6-501 and 0.1-15 ng g-1 for soil and 1.0-2599 and 0.3-4.7 ng g-1 for sediment samples, respectively. BDE-209 was the most abundant PBDE congener, indicating that deca-BDE accounts for most of the total PBDE emitted in the environment of the Punjab Province. The lower average fractions of anti-DP showed significant differences to those of the technical mixtures, indicating lack of DP production source in Pakistan. In general, POPs level in the current study were found lower and/or within the range of other studies reported throughout the world. Conversely, OCPs and PCBs concentrations in riverine sediments were found much higher than previously reported in Pakistan. Air–soil exchange of POPs was estimated by calculating the fugacities in soil and air samples. In the present study, fugacity fractions (ff) values suggested that soils are acting as a secondary source of DDTs to contaminate the atmosphere at certain sampling stations while other areas showed equilibrium and/or atmospheric deposition status. By our results, it is concluded that globally banned organic pollutants are still used/emitted in the catchment area of River Ravi. Our findings also drew attention that elevated levels of DDTs, HCHs, PCBs (tri- and tetra-), and BDE-209 in the study area must be considered as an important environmental issue and steps should be taken to control excessive discharge of organic pollutants in the local environment. The current study also encouraged to conduct more detailed studies to evaluate the ecotoxicological effects of these contaminants in the environment of Pakistan.
