مولانا سعید احمد اکبر آبادی

مولانا سعیداحمد اکبرآبادی
اس سے زیادہ دلدوز خبر،مفتی عتیق الرحمن ؒ کے وصال کے بعد ندوۃ المصنفین ماہنامہ برہان کے لیے کوئی دوسری نہیں کہ ۲۴؍ مئی مولانا سعید اکبرآبادی کاکراچی میں انتقال ہوگیا۔اِنَّا لِلّٰہِ وَاِنَّا اِلَیْہِ رَاجِعُوْنَ ْ
مولانا سعید احمد اکبرآبادی کی رحلت،علمی، ادبی، اوردینی، اور صحافتی دنیا کا ایک ایسا نقصان ہے جس کی تلافی کی کوئی صورت بظاہر موجود نہیں ہے وہ ان نادر شخصیتوں میں سے جن کے اندر قدیم اورجدید علوم جمع ہوجاتے ہیں اور وہ زمانہ کو اپنی خداداد ذہانت اور طبائع کی روشنی سے منّور کرنے کاایسا عظیم الشان کام انجام دیتے ہیں، جوقدیم علوم کے ماہرین اور جدید علوم کے علمبردار وں سے الگ الگ صورت میں ممکن نہیں۔ مولانا سعید احمد اکبرآبادی ایک طرف علامہ انور شاہ کشمیریؒ کے ذریعہ اورواسطے سے ،اس سلسلۃ الذہب سے منسلک نظرآتے ہیں،جواسرار علوم نبوت کے محرموں اورفقہ وحدیث کے بالغ نظر عالموں، اسلامی شرع اوردینی کمالات کے حامل شخصیتوں کاایک ایسا قافلہ ہے، جس نے دینی علوم کوتحقیقی صلاحیتوں کے قالب میں ڈھال کر ہرزمانہ اور ہرعہد کے مطابق بنانے اور اس کی رہنمایانہ استعدادقائم ر کھنے میں ناقابلِ فراموش حصّہ لیا۔ دوسری طرف سے وہ جدید علوم سے پوری طرح واقف، اور دنیا میں سائنسی اورصنعتی اورمعاشی انقلابات کے اثرات ونتائج سے مکمل طورپر باخبر اور نئے زمانے کے تقاضوں کاپورا شعور رکھنے والے ایک دانشور تھے، جوقدیم علوم کی آب و تاب،مذہبی روایات کے تقدس کی برقراری اور اصول واحکام دین کی پاسداری بلکہ نگہبانی کافرض آدھی صدی سے بھی زیادہ مدّت تک انجام دیتے رہے۔وہ ایک طرف مفتی عتیق الرحمن عثمانی ؒ،مولانا حفظ الرحمن سیوہاروی ؒ، مولانامحمد یوسف بنوری ؒ، مفتی محمد شفیع دیوبندیؒ،قاضی زین العابدین سجاد میرٹھی(تعالیٰ اﷲ عمرہٗ) مولانا احمدعلی لاہوریؒ،اورمولانا قاری محمد طےّب قاسمیؒ ،جیسے نابغۃ العصراور فقید المثال ماہرین علوم شریعت اور...

Reconciliation Process in Afghanistan and Pakistan as Cardinal Player

Afghanistan is in state of war for almost 40 long years but the political dynamics got changed after 9/11. Since the war on terror started facets of peace talks launched without meaningful end. The reconciliation process in Afghanistan had immediately started after establishment of Afghan interim government in 2001. Till 2016 mid, four different reconciliation /reintegration processes were launched by the USA and Hamid Karzai government with Afghan Taliban. The new elected president Ashraf Ghani ended all such processes in 2016 but showed willingness again in 2018 for direct peace talks between USA and Taliban clerics. In the current political scenario, Afghan reconciliation process is back on track with direct peace talks between USA, Taliban and Afghan Government along other international actors. However, Taliban were not ready to sit with the Afghan Government and this is where the Pakistan played as key to Afghan peace process. The focus of this research article is to find the challenges and opportunities of this peace process; Pakistan’s role as cardinal player can consolidate the peace process in Afghanistan. Furthermore, this research will give future recommendations for the peace process in Afghanistan.

Assessment of Phytoremedial Potential of Some Commercial Tree Species As Irrigated by Wastewater

Over population, urbanization and industrialization are profoundly polluting our environment with various types of organic and/or inorganic pollutants, especially, the heavy metals. This is the outcome of blind use of fertilizers, pesticides, petroleum products and raw wastewater for irrigation in agriculture. Urban wastewater is one of the sources of heavy metal, causing serious threat to urban and agro-ecosystems. A newly emerging phytoremedial (eco-friendly) approach is being used globally to minimize the heavy metal pollution from air, soil and wastewater. This research work was designed to examine the potential of woody plants to reduce heavy metal pollution. The present study was conducted during 2012-2014 in the Department of Forestry and Range Management, University of Agriculture, Faisalabad. The study was carried out to assess phytoremedial potential of four tree species viz: Acacia ampliceps, Acacia nilotica, Azadirachta indica and Morus alba. The randomly selected four species were linearly planted in 2008 in field experimental area, Directorate of Farms University of Agriculture, Faisalabad (Pakistan) under three different sources of irrigation (treatments) viz: canal water (IS1), domestic wastewater (IS2) and municipal wastewater (IS3). As preliminary study, plant data were collected and analyzed for growth behavior and heavy metal uptake by the tree species under each source of irrigation. Secondly, a pot experiment was conducted to study the response of the same tree species as irrigated by wastewater. Tree seedlings were grown in plastic pots by applying prescribed types of irrigations (treatments). In the third experiment, tree seedlings of four species were grown in polythene bags and subjected to irrigation water of four qualities (treatments) viz: Tap water (control), distilled water with three different levels of Cd and Pb (a- 0.02 mg Cd and 10 mg Pb L-1, b- 0.04 mg Cd and 20 mg Pb L-1, c- 0.06 mg Cd and 30 mg Pb L-1). The focus of the third study was to reasses heavy metal uptake potential of the same species under controlled conditions. Data (from three experiments) revealed that A. ampliceps got top ranking with regard to heavy metal (Cd & Pb) uptake showing no or limited growth stress. Whereas, M. alba was found least active in this regard. For instance, A. ampliceps absorbed average concentration 12.79 mg kg-1, 3.38 mg kg-1 and 1.91 mg kg-1 of Cd contents in first, second and third experiments, respectively. Similarly, it absorbed average concentration 85.93 mg kg-1, 70.93 mg kg-1 and 31.70 mg kg-1 of Pb in the same experiments, respectively. However, M. alba absorbed average concentration 4.22 mg kg-1, 1.42 mg kg- 1 and 0.49 mg kg-1 of Cd in first, second and third experiments respectively. Whereas, Pb uptake by M. alba in the same experiments was an average concentration: 27.34 mg kg-1, 12.34 mg kg-1 and 6.36 mg kg-1 respectively. Based on our findings, it was concluded that Acacia ampliceps is the best phytoremedial tree species for polluted soil and water contaminated with Cd and Pb metal. Raising A. nilotica and M. alba as browse species in not risky for our food chain system. On the other hand, A. ampliceps should not be used for forage purpose when planted with wastewater irrigation.
