ڈاکٹرشہزاد احمد کی شاعری کا فنی جائزہ
سہل ممتنع
ڈاکٹرشہزاداحمد نعت خوانی سے نعت گوئی کی طرف مائل ہوئے ہیں۔ انھیں خیال آفرینی و مرصع کاری سے زیادہ ابلاغ کی فکر رہتی ہے۔ اس لیے وہ کلام میں سادگی کو اہمیت دیتے نظر آتے ہیں۔اُن کے کلام میں بھاری بھرکم تراکیب کی جگہ عام بول چال کے سادہ الفاظ ادائے مطلب کے لیے استعمال ہوئے ہیں۔ ان کی نعت کی مرکزی خصوصیت سہل ممتنع ہے جس کے بارے میں مولانا حسرت موہانی لکھتے ہیں :
’’سہل ممتنع سادگی وحسن بیان کی اُس صنف کا نام ہے جس کو دیکھ کر ہر شخص بظاہر یہ سمجھے کہ یہ بات میرے دل میں بھی تھی اور ایسا کہنا ہر شاعر کے لیے آسان ہے مگر جب کوشش کرکے ویسا لکھنا چاہے تو نہ لکھ سکے۔‘‘ (۲۴)
یہی سادہ اسلوب ہمیں ڈاکٹر شہزاد احمد کی نعت میں بڑے سلیقے سے برتا ہوا ملتا ہے۔ مثال میں دو شعر ملاحظہ ہوں:
آپ صرف اپنے محبوب کا
مجھ کو شیدا بنا دیجیے
پھر جہاں میں ہے تیرگی چھائی
اپنا جلوہ دکھائیے آقاؐ
غنائی لہجہ
شاعری میں موسیقیت نہ ہو تو کلام فصاحت سے کوسوں دُور رہتا ہے۔ موسیقیت کے لیے آواز کے زیرو بم کے استعمال سے واقفیت ضروری ہے۔ ڈاکٹر شہزاد احمد چوں کہ نعت خوانی سے بھی وابستہ ہیں۔ اس لیے اُن کے کلام میں غنائیت کا عنصر اوج پر ہے۔ پروفیسرنویدعاجز ؔ اس بارے میں یوں رقم طراز ہیں:
’’انھوں نے نعتیں محافل میں پڑھنے کے لیے لکھی ہیں، اس لیے اُن کی سب سے بڑی خوبی موسیقیت اور روانی ہے۔ ’’حبیبی یارسول اللہ، درودتم پر سلام تم پر اور بسم اللہ ‘‘ کی ردیف میں کہی گئی نعتیں مترنم لہجے کی حامل ہیں۔‘‘(۲۵)
ڈاکٹر شہزاداحمد کے کلام میں روانی اور مترنم لہجے کے اشعار کی کمی نہیں۔ چند مثالیں ملاحظہ ہوں:
Background: Foreign body aspiration (FBA) is a commonly observed, fatal but preventable condition in children. To reduce the incidence of FBA, it is essential to provide parents with knowledge and guidelines regarding the prevention and management of FBA. Objectives: To assess parental knowledge and parental role in the prevention and first aid management of foreign body aspiration in children. Methods: A descriptive cross-sectional study was carried out at Mayo Hospital, Lahore from January 2019 to September 2019. After IRB approval and informed consent, 151 parents were enrolled through convenient sampling. Data were recorded in a structured questionnaire and analyzed through SPSS version 26. Results: Breathlessness and vomiting were recognized as symptoms of FBA by 49.7% & 7.3% of parents respectively. Hand clutched to throat, color & voice change were recognized as signs by 6.6 %, 9.9 % &10.6 % of the parents. As a first aid measure, 66.2% of individuals knew about back slaps, while only 2% were aware of abdominal thrusts. Literate parents were well aware of the facts that children under the age of three should not consume seeds, hazelnuts, and hard nuts and the child should not laugh or talk while eating compared to illiterate parents (p<0.05) Conclusion: The majority of the parents are not well aware of signs, symptoms, preventive measures and first aid measurements regarding FBA.
The newborn phenomenon of temporal cloaking is investigated under the e®ects of Doppler broadening and Kerr nonlinearity in di®erent atomic me- dia. The optical properties of these media are manipulated in such a manner that a time gap is created in the propagating probe light where events or information can be transmitted undetected. To create the cloaking time gap, the enhanced subluminal and superluminal behaviors of the probe ¯eld are focused. The opened temporal gap is closed by an inverse process that involves reverse modi¯cation of the optical properties of the medium. Ini- tially, we consider a ¯ve-level M-type atomic con¯guration of rubidium. The concept of Doppler broadening is introduced along with the superposition of the double resonant ¯elds in the system. Phase shift variations are caused in the medium which result into a signi¯cant delay and advancement of the probe pulse. The delay and advancement times lead to the generation of a time hole for concealing information in the temporal domain. A microsecond time gap is attained without signi¯cant distortion in the pulse shape. The time gap is further increased to several orders of microseconds with increase in the Doppler width. Next, we investigate propagation of the light pulse in a four-level Doppler broadened sodium atomic system. The possibility of creating a temporal gap is discussed on the basis of spectral hole burning in the system. The probe pulse is observed to delay in the hole burning region while it advances in the nearest neighboring region. A cloaking time gap of the order of microseconds is achieved in the slow and fast light regime. The time gap is modi¯ed with the inverse Doppler e®ect. The time gap can also be tuned and modi¯ed with the strengths of the coupling ¯elds, if the Doppler width is kept constant in the system. Finally, we extend our studies to the three-level rubidium atomic system. The pulse delay and advancement vi times are observed at speci¯c system parameters in the presence of self-Kerr ¯eld e®ect. The delay and advance times are enhanced with increase in the intensity of self-Kerr ¯eld. A cloaking time gap of the order of nanosecond is created in the observed fast and slow light. Increase of the time gap is observed with increase in the intensity of self-Kerr nonlinearity. The time gap is enhanced to several orders of nanosecond, su±cient to hide any prac- tical event. The time gaps are closed by reverse manipulation of the optical properties. Our results may contribute to strengthening the idea of hiding events in successive temporal gaps for achieving enhanced security of the communication systems.
