مولانا شاہ عبدالقادر رائے پوری

مولانا شاہ عبدالقادر رائے پوری
افسوس ہے ابھی حضرت مجاہد ملت کے ماتم کے آنسو خشک بھی نہیں ہوئے تھے کہ ملت اسلامیہ کے لیے ایک دوسرا حادثۂ جاں گداز پیش آگیا اورطریقت و معرفت ربانی کاآفتاب غروب ہوگیا۔حضرت مولانا شاہ عبدالقادر صاحب رائے پوری اکابر مشائخ دیوبند کے سلسلہ کی آخری کڑی تھے۔عمر کم وبیش ۹۰برس کی پائی۔مگرچاربرس پہلے تک قویٰ بڑے اچھے تھے اور انڈوپاک کے ہزاروں مسلمان بقدر استعداد اس سرچشمۂ روحانیت وانابت الی اﷲ سے مستفید ہوتے تھے۔ آپ کااصل وطن گرداسپور تھا۔آغاز شباب میں ہی مرشد کی تلاش میں نکل پڑے اورآخر حضرت مولانا شاہ عبدالرحیم صاحب رائے پوری جوحضرت مولانا گنگوہیؒ کے خلیفۂ خاص اوراکابردیوبند میں ایک ممتاز ورفیع مقام کے مالک تھے، اُن کی خدمت میں پہنچ کر گوہر مقصود پالیا۔چنانچہ آپ اس درگاہ قدس سے ایسے وابستہ ہوئے کہ پوری زندگی یہیں گزار دی۔تقسیم کے بعدہی مشرقی پنجاب میں جوطوفان امڈا اُس نے کتنی آبادیوں کوویرانہ بنادیا۔مگر شاہ صاحب تھے کہ اپنی جگہ پرکسی قسم کے خوف وہراس کے بغیر جمے رہے اوراس کااثر یہ ہواکہ اس نواح کی تمام مسلمان آبادی محفوظ رہی۔ مشائخ دیوبند کی ایک عام خصوصیت ہے سلوک ومعرفت کے اعلیٰ مقام پر فائز ہونے کے ساتھ شریعت کے احکام واوامر اورسنت واسوۂ نبوی کامکمل اتباع اوراس سے انحراف کاکسی حالت میں بھی روادار نہ ہونا۔یہ صفت حضرت مرحوم میں بھی بدرجۂ اتم موجود تھی۔ اس عام خصوصیت کے علاوہ ہربزرگ کے کچھ اپنے خاص احوال وکوائف ہوتے ہیں اوراس کا سبب یہ ہوتاہے کہ کمالات واوصاف نبوی میں سے اُس پرکسی خاص ایک وصف کاغلبہ ہوتاہے۔مثلاً کسی میں صفت علم غالب ہوتی ہے اورکسی پرصفت خلق، کوئی شان جمالی کا مظہر ہوتاہے اورکوئی شان جلالی کا۔اس اعتبار سے شاہ صاحب پرصفت فقرواستغناء،سادگی وبے تکلفی اورصفت محبت کااستیلا تھا۔محبت خود اپنے اندر مقناطیسی کشش رکھتی...

Mohammad Ali Jinnah: His Vision and Legacy

Eighty years ago, when Mohammad Ali Jinnah started his address to the 1938 Session of the All-India Muslim League, he spoke in Urdu: Jab hum Patna ka tariki shahr mein aya. Immediately the public started shouting: “English! English!” and the Quaid-i-Azam resumed his address: “When I came to this historic city of Patna…”. What was the reason behind the public’s odd demand? At that time it was clearly understood that Independence had to be taken from the British. The Muslims knew that they needed a leader who could speak to the colonial masters in their own language. That is why, though only a fraction of the gathering could speak or understand the language, they wished their leader to speak in English

Determination of Chlorinated Pesticides and Degradation of Chlorpyrifos in Water by Advanced Oxidation Process

Pesticides contamination is a wide spread source of environmental pollution and a matter of concern all over the world. In recent decades, the use of pesticides for agricultural purposes has steadily increased. Surface and ground water contamination due to extensive use of pesticides is a serious threat to the environment and human health. Pesticides are very toxic compounds causing various diseases. Therefore, in this research work, efforts have been made to determine various chlorinated pesticides contamination in water samples of selected areas of Khyber Pukhtoon Khwa, Pakistan. The determination of 20 chlorinated pesticides have been performed in surface and ground water samples collected from different districts (Peshawar, Mardan, Sawabi and Charsadda) of Khyber Pukhtoon Khawa, Pakistan. A total of 239 water samples (157 surface and 82 ground water samples) were collected from various locations of selected areas. The number of surface water samples, collected from Peshawar, Mardan, Charsadda and Sawabi districts were 59, 42, 30 and 26 samples, respectively. Similarly, 29, 24 and 29 ground water samples were collected from Peshawar, Charsadda and Mardan districts, respectively. Solid phase microextraction (SPME) technique was used for various pesticides extraction from water samples. Chlorinated pesticides were determined in water samples using SPME coupled with gas chromatography and electron captured detector (SPME-GC-ECD) method. Using this method, the plots of chlorinated pesticides concentrations and peak areas showed good linear correlation with R2 values in the range of 0.9887 to 0.9999. The percent recovery found at 1 μg L-1 and at 2 μg L- 1 concentration of pesticides ranged from 89.9 ± 3.9 % to 106.0 ± 2.3 and 88.5 ± 2.6 to 109.2 ± 2.9 %, respectively. The lower limits of detection for all 20 organochlorine pesticides were found significantly less than their maximum contamination levels. Among the various pesticides analyzed, β-BHC, γ-BHC, heptachlor, aldrin, α- chlordane, endosulfan I, 4,4''-DDE and dieldrin were detected in most of the water samples. However, other pesticides, like heptachlor epoxide, γ-chlordane, endrin, 4,4''-DDD, endrin ketone, 4,4''-DDT, methoxychlor, α-BHC, δ-BHC, endosulfan I, endosulfan II, endrin aldehyde and endosulfan sulfate were mostly present in only few water samples in the present investigation. Chlorpyrifos and monocrotophos are very toxic organophosphorous pesticides and have more importance due to their extensive use, large distribution and persistence in the environment. They are very dangerous by all routs of absorbtion, such as inhalation, ingestion and skin contact and producing various diseases. In the present study, the irradiation of chlorpyrifos and monocrotophos in aqueous solution by gamma-rays were investigated on a laboratory scale and their degradation efficiency was studied. The GC-ECD and HPLC (High performance liquid chromatography) were used for analysis of chlorpyrifos and monocrotophos, respectively. Aqueous solutions of different concentrations of chlorpyrifos compound (200–1000 μg L-1) were irradiated to different doses (30–575 Gy). Gamma irradiation showed 100 % degradation efficiency (η) for a 500 μg L-1 solution at an absorbed dose of 575 Gy. The dose rate of source was 300 Gy h -1. The radiolysis kinetics for decay of chlorpyrifos was pseudo-first order. The dose constants determined in this study ranged from 8.2 ´ 10-3 to 2.6 ´ 10-2 Gy−1, and decreased with an increase in the initial concentration of chlorpyrifos. The radiation chemical yield (G-values) for the loss of chlorpyrifos was found to decrease with increasing absorbed dose. The gamma radiation induced decomposition of monocrotophos aqueous solution at various concentrations (60-150 mg L-1) was carried out and its removal efficiency (η) was investigated. At 1200 Gy absorbed dose of gamma irradiation, monocrotophos solution (60 mg L-1) showed 100% degradation. The dose constants investigated in this study ranged from 1.4 ´ 10-3 to 3.0 ´ 10-3 Gy-1. The monocrotophos solution prepared in tap water showed lower degradation than that solution prepared in Milli Q water. The effect of radical scavengers, such as tert-butanol, iso-propanol, H2O2, CO3-2, HCO3-, humic acid, NO3- and NO2- as well as saturation of solutions by N2, N2O or air on the degradation of chlorpyrifos and monocrotophos were also studied. The results showed that the oxidative hydroxyl radical (•OH) was the most important in the degradation of chlorpyrifos and monocrotophos, while the reductive radicals, aqueous electron (e-aq) and hydrogen radical (H•) were of less relative importance for the degradation of these two pesticides. The inorganic by-products of chlorpyrifos (Cl -, SO 4-2 and PO4 -3) and monocrotophos (NO3-, NH4+ and PO4-3) were quantitatively determined by ion chromatography (IC). The organic intermediates of monocrotophos degradation were determined by HPLC/MS and UPLC/MS/MS. A detail mechanism pathway for degradation of monocrotophos by gamma irradiation has been proposed.
