مولانا محمد الحسنی

مولانا محمد الحسنی
ایک عربی شاعر نے کہا ہے:
من لم یمت عبطۃً یمت ھرما
1للموت کاساًفالمرء ذائقاً
¹’’جولوگ جوانی میں نہیں مرتے وہ بوڑھے ہوکرمریں گے۔بہرحال موت کی شراب ہرشخص کے لیے چشیدنی ہے۔‘‘
افسوس ہے گذشتہ مہینہ ہمارے علوم دینیہ و عربیہ کے دومرکزوں میں چند روز کے فرق سے شعر میں مذکوردونوں قسم کی حسرتناک موتیں واقع ہوئیں، پہلا واقعہ دارالعلوم ندوۃ العلماء لکھنؤ میں مولوی محمدالحسنی کی اچانک وفات کاپیش آیا۔ مرحوم صحیح معنی میں متنبی کے اس شعر کے مصداق تھے:
وشیخ فی الشباب ولیس شیخاً
-یسمی کل من بلغ المشیبا
وہ کہنے کومولانا سید ابوالحسن علی میاں کے بھتیجے تھے مگردرحقیقت وہ مولانا کے لیے فرزند حقیقی سے بڑھ کرتھے۔مولانا نے اپنے فیض تعلیم وتربیت اورتوجہ خصوصی سے اس جوہر قابل کوایسا چمکایا کہ مرحوم عربی ادب وانشا میں مولانا کے مثنی بن گئے۔عرصہ سے’’البعث الاسلامی‘‘کے رئیس التحریر تھے، اس حیثیت سے انھوں نے جومقالات اوراداریے لکھے انہوں نے ہندوبیرونِ ہند کے اسلامی حلقوں میں دھوم مچادی۔ ان کی کتاب’’الاسلام الممتحن‘‘جوعالم اسلام اور خصوصاً عرب ممالک کے معاملات ومسائل سے متعلق اُن کے بیس برس کے اداریوں اورمقالات کامنتخب مجموعہ ہے، وہ عرب میں اس درجہ مقبول ہوئی کہ چندبرسوں میں اس کے متعدد ایڈیشن چھپ چکے ہیں۔ وہ اردو زبان کے بھی ادیب تھے۔مصنف اورمترجم کی حیثیت سے اس زبان میں بھی ان کی متعدد یادگاریں ہیں۔عمل وکردار اوراخلاق وعادات کے اعتبارسے وہ اپنے خانوادۂ والاتبار کی روایات کامکمل نمونہ تھے۔یعنی نہایت دیندار، صالح، متواضع، فقیر منش، طبیعت کے نہایت غیور و خوددار، خاموش اور باہمہ و بے ہمہ، دنیا اور اس کے زفارف عیش و عشرت سے قطعاً بے نیاز و روگرداں، عمر چالیس کے لگ بھگ ہوگی۔
؂ خوش درخشید و بے شعلۂ مستعجل بود ۔
رحمہ اﷲ رحمۃ واسعۃ
[ جولائی۱۹۷۹ء]

Mīthāq Al-Madīnah: A Universal Charter of Peace an Analytical Study in the Modern Socio-Political Context

Different religious, political and social leaders tried their best to establish peace and prosperity in the society in different phases of the human history. An influential effort out of these efforts is that of the Prophet (r) Muḥammad. The Prophet (r) faced a pluralistic society of different faiths and religions in Madīnah. So, to make a better relationship and establish peace between the Muslims and the other communities of Madīnah, an agreement, which is called Mīthāq al-Madīnah, was made. Mīthāq al-Madīnah was not only a deed, but it presents all those principles and regulations, which were mandatory for peace building in a state or society. The excellent aspect of this charter is that the recipients of this charter were not the Muslims only, but a pluralistic society of different faiths. These communities were bound to establish peace with an agreement. This charter is an excellent model of peace, prosperity, freedom and human rights. According to this charter, all the parties were free with their religious beliefs and social interests. It was also the constitution of Madīnah. The renowned Muslim scholars are unanimously agreed that it was the first written constitution of the world. This agreement provides all other communities of Madīnah (the Jews, the Christians, and the polytheists) equal rights and freedom. Consequently, the charter of Madīnah can become a base for enduring peace and peaceful coexistence in a pluralistic world for the sake of the welfare of the human beings.

Synthesis and Applications of Reactive Triazine Based Uv Protectors for Textile

Human body is very delicate towards harsh environmental variations. High energy UV radiations intentionally or unintentionally interact with our skin and eyes, causing some acute effect such as, photokeratitis, skin aging and also some chronic effects like melanoma skin cancer and DNA damage. Clothing is an important precautionary measure to combat with these damages, but low weight and high porosity of cotton fabric make it unfit for protection against UV rays. Hence, to improve the protection factor of white cotton fabric, computational approach was utilized to search the effective UV absorbers for cotton fabric. The Density Functional Theory (DFT) theory with three functionals was utilized to study the design molecules and results indicated that all the five design molecules (1-5) absorbed inthe UV region of the solar spectrum. These deigned molecules were synthesized via a condensation reaction and their structure confirmation attained through UV/Vis., FTIR and ESI-MS analysis. The theoretically calculated λmax and experimental λmax of all the five UV absorbers were in close agreement. The cottonfabric was treated with designed and synthesized UV absorbers via the exhaust method of dying and its processing conditions optimized by adapting a statistical design “central composite rotatable design” of response surface methodology. The outcomes directed that all the synthesized molecules showed 65-78 % exhaustion and 62-80 % fixation at the acquired optimized conditions. Maximum exhaustion with cotton fabric was presented by 1 and minimum shown by 5. The protection factor of the treated cotton fabric was assessed and results directed that the treated fabric with 1-4 fells in the very good Ultraviolet Protection Factor (UPF) range at 3 % concentration while fabric treated with 5 fells in good range. The UPF increased as follows: 5 <4 < 2<3<1. Whiteness index test results revealed that all the synthesized molecules did not decrease the whiteness of the fabric as much at 3 % concentration, but after exposition to light fastness testing decreased its whiteness little bit as compared to standard. Washing test results indicated that UPF of treated fabric decreased after washing process, with UV absorbers (1-4), it remained in the very good range of UPF after ten washings. While the 5 showed more reduction in UPF value after washing. Degradation studies revealed that synthesized molecules were degradable by safer advance oxidation process technology. Current study opened a new prospect for search of such molecules having more persistent nature after laundry action.
