ہاشم شاہ(۱۷۵۶ئ۔۱۸۲۱ئ) میں موضعجگد یوکلاں تحصیل اجنالہ میں پیدا ہوئے۔ آپ کے والد حاجی محمد شریف اپنے عہد کے کے پیرِ طریقت تھے۔ ہاشم نے انھیکے ہاتھ پر بیعت کی۔ آپ کے والد مختلف علوم اور زبانوں کے ماہر ہونے کے علاوہ حکیم حاذق بھی تھے۔ مہاراجہ رنجیت سنگھ جب ان کے علاج سے صحت یاب ہوا تو خوش ہو کر تھرپال نزد ریہ نارووال ان کو انعام میں دیا۔ ہاشم تا دمِ مرگ ۱۸۲۱ء یہیں رہے(۶) سرور ارمان نارووال کے شعرا کے تذکرے میں ہاشم شاہ کے بارے میں رقمطراز ہیں:
ہاشم شاہ نے فارسی‘ پنجابی اور اردو میں شاعری کی مگر ان کی شہرت کا بڑا سبب ان کی لکھی ہوئی عشقیہ داستاں سسی پنوں ہے۔ جس سے ان کا شمار پنجابی کلاسیکی شعرامیں ہوتا ہے۔ اس کے علاوہ ہاشم شاہ نے سوہنی مہینوال‘ شیریں فرہاد‘ لیلیٰ مجنوں ‘ ہیر رانجھا اور دوہے بھی پنجابی زبان میں لکھے۔(۷)
ہاشم شاہ عشقِ حقیقی کے قائل تھے۔ ان کے آبائو اجداد میں سب پیر اور روحانی پیشوا تھے۔ آپ نے باطنی طور پر حضرت پیر عبد القادر جیلانیؒ سے روحانی فیض حاصل کیا۔ نمونے کے طور پر کچھ اشعار ملاحظہ ہوں :
اس گناہیں کے لیے یا پیر غفاری کرو
اب تو کچھ پردہ نشیں پر حال ستاری کرو
دستگیری کجیو ڈرتا ہے ہاشم پر گناہ
دستگیر بے کساں یا غوث الاعظم بادشاہ
(۸)
کہاں سکندر کہاں ہے دارا جام کہاں ہے جم کا
جن کی تیغ سے دیو بھی کانپے دل دہلے رستم کا
ان کی راکھ ملے نہ ڈھونڈے دنیا گھر ہے غم کا
ہاشم جان غنیمت جانو نہیں بھروسا دم کا (۹)
پھول اور کانٹے دونوں دیکھو ایک جگہ ہوں پیدا
اک شب پھول کی عمر‘ یہاں پر...
In the present age, youth occupy an important position and can play a very important role in reforming and improving the world conditions. In Quran several methods are suggested for character building of youth for example following “Uswa-e-Hasna” and by preaching and motivation of youth the fear Allah, the crated in their heard for reforming them. In some cases, the punishment can also reformed of youth. Youth is an important entity of any human society. Particularly in an Islamic society, youth has great significance. Youth is considered as a junction of past, present and future. The role of young generation cannot be neglected in the building of character, changes in circumstances and development of society. Youth should play a positive and effective role against various evils, which are prevalent in human society. What can be the religious social, political, ethical and educational duties of the Muslim? How can they play their role in reformation of society? How can they be bright stars of their country by fulfilling their duties? How can the whole humanity and particularly Islamic Ummah get benefits from their youth? The answers to these questions are central idea and theme of this article, generally in the light of Islam and particularly in the light of seerah-un-nabwiyia. In following lines, it has been tried to impart feelings of high self-esteem in the young generation who have forgotten it. It is an effort to motivate the youth for practical actions.
Polystyrene is a rigid plastic that is commonly used in crystalline and foamed form. Biodegradation of polystyrene is very slow in natural environment and it persists for longer period of time as solid waste. The aim of the study was to investigate the biodegradation process of polystyrene and explore the ways to enhance the biodegradation process. Soil burial method was used to isolate microorganisms. The plastic films recovered from soil after 8 months were incubated on mineral salts media (MSM) agar plates for 3 months to get the growth of only those microorganisms that were able to grow with polystyrene for longer time. Six fungal and five bacterial stains were isolated and identified. Three fungal isolates were selected on the basis of biodegradability of polystyrene films in shake flask transformation experiments analysed by Fourier transform Infrared (FTIR) spectroscopy. The selected fungal strains were characterized taxonomically on the basis of sequence homology of conserved regions of 18S rRNA and were identified as Rhizopus oryzae NA1, Aspergillus terreus NA2 and Phanerochaete chrysosporium NA3. The 18S rRNA sequences were deposited in NCBI database with accession numbers in Genbank FJ654430, FJ654431 and FJ654433 for strain NA1, NA2, NA3 respectively. The biodegradation of polystyrene was studied by CO 2 evolution test (Sturm test) all the isolated showed higher CO 2 levels in the test as compared to control showing effective mineralization of polystyrene. Biodegradation studies in liquid media with polystyrene films, expanded polystyrene (EPS) films and beads were conducted in the static and shake flask (120rpm) fermentation experiments at 30 oC. Scanning electron microscopic (SEM) analysis showed that the fungal isolates were able to establish mycelia on the polymer surface and maximum growth was observed in glucose added mineral salts media. FTIR spectra of the treated films showed increase in absorption spectra around 536 cm -1 , 748 cm -1 (mono substituted aromatic compound), 1026 cm -1 , 1450 cm -1 , 1492 cm - 1 (C=C stretching vibration of aromatic compounds), 2916 cm -1 , 3400 cm -1 (aryl-H stretching vibrations). Major changes were observed in 1000-1700 cm -1 and 3400 cm -1 region which indicated depolymerisation and degradation into monomers. xiiMolecular weight distribution was studied by gel permeation chromatography (GPC). The weight average molecular weight and number average molecular weight increased in the samples of polystyrene films and EPS beads treated with the fungal isolates as compared to control while decreased in case of expanded polystyrene. The polydispersity decreased in polystyrene and increased in EPS films. In proton nuclear magnetic resonance ( 1 H-NMR) spectra of polystyrene and expanded polystyrene intensities of the signals were increased in treated samples as compared to control but treated samples did not show any significant change in the spectra. The degradation products of the polystyrene and expanded polystyrene were analysed by HPLC. 1-phenyl-1,2-ethandiol, 2-phenylethanol and phenyacetaldehyde and styrene oxide, which were oxidation degradation products of monomer styrene, were detected in most of the cases. 1-phenyl-1,2-ethandiol was detected with highest concentration of 21.3 ppm in media sample of polystyrene incubated with A. terreus NA2 in shake flask and 34.7 ppm with P. chrysosporium NA3 in static conditions. Polystyrene films were given pretreatment of UV irradiation (1-2 hr. at λ 254 nm) and heat (60 ̊C and 80 ̊C for 1 hour) and then biodegradation was studied. UV pretreatment of 2 hours showed enhancing effect on biodegradation by fungal isolates indicated a decrease of weight average molecular weight in the treated samples. Heat pretreatments did not show enhancing effect on biodegradation except P. chrysosporium NA3 treatment of heat pretreated polystyrene films. Enhancing effect of glucose on biodegradation of polystyrene films was observed in FTIR spectral analysis, when glucose was used as additional carbon source in mineral salts media, The soil buried films of polystyrene for six months showed very significant degradation in FTIR and GPC analysis. The scanning electron micrographs of the treated films from all the samples also confirmed the biodegradation process by showing some changes in structure and colonization of fungi on the films. The selected fungal strains are capable of utilising polystyrene as a sole carbon source and have potential to be used for polystyrene biodegradation in the environment.
