خالد جاوید کی نعت گوئی

خالد جاوید کی نعت گوئی

ادب میں مذہبی شخصیات کی تعریف و ثناء کا سلسلہ اس وقت سے جاری ہے جب سے انسان نے اپنے جذبات و عقیدت کو الفاظ میں بیان کرنا شروع کیا ہے یہ سلسلہ دنیا کے ہر ادب اور خطے میں موجود ہے۔ہر مذیب کو ماننے والے اپنے اپنے انداز میں ان ہستیوں سے اظہار محبت الگ الگ انداز میں کرتے ہیں۔کہیں ان کی شان میں گیت گائے جاتے ہیں اور کہیں قصیدے پڑھے جاتے ہیں۔اظہار کا ذریعہ کوئی بھی ہو،اصل بات اس عقیدت کی ہے جو ان کے من میں ان ہستیوں کے بارے میں ہے۔

ان ہستیوں کی مدح سرائی انتہائی مشکل کام ہے اس لئے کہ اس ہستی کے شایان شان الفاظ کا انتخاب ایسا ہونا چاہیے جس میں آپکی عقیدت کے ساتھ اس ہستی کی ظاہری و باطنی خوبیاں بھی کْھل کر سامنے آ ئیں،تاکہ پڑھنے والے پر اس کا اچھا اثر پڑے اور وہ ان کے نقش قدم پر عمل پیرا ہونے کی کوشش کرے۔مدح سرائی کرتے وقت مدح نگار کو انتہائی احتیاط سے کام لینا پڑتا ہے۔کیونکہ اس میں مبالغہ آمیزی کا خطرہ بہت زیادہ ہوتا ہے۔مگر جو مدح نگار ان ہستیوں کی محبت میں ڈوبا ہوا ہو،وہ یہ کام نہیں کر سکتا۔ایسے مدح نگاروں میں ایک نام خالد جاوید کا بھی ہے۔

خالد جاوید کی عقیدتوں کا سفر ’’خوشبوئے مدینہ‘‘ کی صورت میں شائع ہو کر عاشقان رسولﷺ میں عقیدت و محبت بانٹتا ہوا دیکھائی دیتا ہے نعتیہ مجموعہ کلام میں ہر جگہ آپ کی نبی پاک سے محبت عیاں ہورہی ہے۔نعت کہنا ہر شاعر کے بس کی بات نہیں یہ کام خالد جاوید جیسا عاشق رسول ہی کر سکتا ہے کیونکہ یہ سب نبی پاک کی نظر کرم سے ممکن ہوتا ہے جب آپ کی نعت...

احادیث ِنزو لِ مسیح ابن مریم علیہما السلام میں قادیانیوں کی تاویلات کا تنقیدی جائزہ A Critical Review of Interpretations of Qādiyānies in Aḥadīth of Nuzūl Al-Masīḥ Ibn e Maryam (علیہما السلام)

The negation of the crucifixion and murder of Maseeh علیہ السلام and the ascension to heaven are mentioned in the Holy Qur'an and the revelation to the earth is mentioned in the authentic Ahadith. The Holy Qur'an and Hadith do not contradict each other on the ascension and revelation of Maseeh علیہ السلام. Mirza Ghulam Ahmed Qadiyani interpret those thirty verses of the Holy Qur'an are about the death of Maseeh علیہ السلام which have nothing to do with his death. The Hadiths of the revelation of Maseehعلیہ السلام benefit from the Holy Qur'an, not derived from any Ijtihad or Israelism. The word death is not mentioned for Essa علیہ السلام in the Holy Qur'an. It is not possible for the Hadith to describe the return of Essa علیہ السلام to earth before the Day of Judgment and let his death be mentioned in the Holy Qur'an. Otherwise, instead of stating the meaning of Holy Qur'an, the Hadith will contradict the Qur'an. The Qur'an mentions the ascension of Essa علیہ السلام to heaven and the Hadith describes the revelation to the earth. There is not a single Hadith that indicates that Essa علیہ السلام refers to Mirza Ghulam Ahmed of Qadian and his descent means that is born from the mothes’s womb, or it is a descent as buroz (بروزی).

Design and Analysis of Shielding Cerrobend Blocks and Investigation of Performance of Thermoluminesce / Photoluminescence-Based Detectors During In-Vivo Dosimetry

The actual dose delivery in radiotherapy is of prime importance, which can only be achieved by using an accurate dosimeter. This work reflects the fabrication of three types of dosimeters that can be applied in radiation dose measurement during radiotherapy and other areas of radiation measurements. LiF is a special material, which when doped with some activators produces a single crystal that acts as a highly sensitive nanophosphor. These nanophosphors have several applications, such as, color center laser, integrated optics and radiation dosimetry. It is widely used in personal dosimetry because of its low energy dependence, tissue equivalency, stability and sensitivity. In this work, we have locally fabricated monocrystalline cubes of LiF doped with Mg, Ti, Dy3+ and Eu3+ by simple chemical coprecipitation method. These dosimeters were annealed at two unique temperatures i.e. at 400ºC and at 600ºC. The synthesized samples were characterized by XRD, SEM, and FESEM, EDX, FTIR for structural and morphological studies. XRD showed the phase of LiF and crystallite size was found around 30 nm. SEM studied the surface morphology of the samples as cubic, while EDX indicated the chemical composition of the nanophosphor. FE-SEM was employed to see the grain and grain boundaries more clearly. Furthermore, FTIR spectra were recorded in order to see the different molecular species and functional groups in these nanophosphors. The spectra revealed the presence of hydroxyl group (–O–H) of the metal hydroxide such as Mg (OH)2, stretching vibrations of rare-earth cations (Dy3+ and Eu3+) and metals oxides, Li-O and Mg-O. To study the PL properties of the two dosimeters (LiF: Mg, Dy3+ and LiF: Eu3+), PL spectroscopy was performed, which confirmed the emission spectra in the visible region of 685 nm for Dy3+and 610 nm for Eu3+. Both emissions occurred in the red portion of electromagnetic spectrum. Finally, the core property of these dosimeters i.e. the TL property was studied from their glow curves. All the obligatory parameters for these dosimeters were carried out; for example, dose sensitivity, dose linearity response, dose fading, dose rate dependency, angle dependency, and energy dependency. The fabricated TLDs and commercially available TLDs were compared both in sensitivity and glow curve peak temperatures. The glow peak temperature was 285 °C to 290 °C while the sensitivity of the fabricated TLDs was about 8 times less than that of commercial ones to lower doses and vice versa. In-vivo dosimetry was performed using Rando-phantom in 5 common radiotherapy treatment sights having Organ at Risk. The OARs were shielded with customized blocks. The shielded OAR dose and the in-field target doses were measured, using the TL dosimeters (LiF: Mg, Ti). The measured dose and the Treatment Planning System (eclipse point dose version) results were compared and both were found well correlated in open areas, and shielded regions.
