نہ کر توں مان وساہواں دا

نہ کر توں مان وساہواں دا
چھڈ جانا ایں پنجرا ساہواں دا

انج عشق دیوانہ کیتا اے
ہو گیا اے حال تباہواں دا

اتوں فجری ویلا آ ہویا
راہ تک تک تیریاں راہواں دا

جیہڑیاں پتر شہید کراندیاں نیں
دھن جگرا اے انہاں ماواں دا

بھانویں لکھ موبائل آ گئے نیں
ہے اپنا رنگ سنیاہواں دا

اینویں رو رو رائیگاں عمر گئی
مُل پیا نہ میریاں ہاہواں دا

جس تھاں تے اوس سلام کیتا
کراں ادب میں انہاں تھاواں دا

پڑھ لکھ کروڑ سلام نبیؐ تے
راہ مل مدینے دیاں راہواں دا

مرے ماں تے پتہ لگ جاندا
کی قدر اے ٹھنڈیاں چھاواں دا

پھرے پیا حنیف ہو دیوانہ
ایہو اثر ہے تیز نگاہواں دا

علم اسباب ورود الحدیث: ایک تحقیقی جائزہ

Asbab-e-worood-e-Hadith means the context of background of a Haith. It is impossible to understand the original myth of hadith without knowing its background and context. This Article presents the concept of asbab-e-worood-e-Hadith. The discussion has been premeditated to explore the meanings and importance of asbab-e-worood. In this regard, keeping in view the nature of topic, the guidance has been sought from the Ahadith of Holy Prophet (PBUH). Asbab-e-worood in its nature having similarities with asbab-e-nazool-e-Quran. This article also describes the relationship between asbab-e-worood-e-hadith and asbab-e-nozool-e-Quran. In this regard some examples have been discussed also. This article also describes how asbab-e-worood is important to specify the meanings of text and explain the textual ambiguities. Key Words: Asbab-e-worood-e-Hadith Asbab-e-Nozool-e-Quran Sabab-e-worood qasasia 4.         Sabab-e-worood sawalia

Three Wave Interactions in Non- Degenerate and Degenerate Magneto-Plasmas

In this thesis we study the parametric decay instability problem (three wave interactions) in classical andquantummagneto‐plasmas.Twocombinationsofthethreewaveinteractionshavebeen investigated.First,theparametricdecayinstabilityofupperhybridwaveintolow‐frequency electromagnetic shear Alfven wave and Ordinary mode radiation has been solved in an electron‐ion plasma immersed in uniform external magnetic field. Incorporating quantum effect due to electron spin, the fluid model has been used to investigate the linear and nonlinear response of the plasma species. It is shown that the spin of electrons has considerable effect on the three‐wave coupling interactions even in classical regime. Secondly,theelectronspin‐1/2effectsontheparametricdecayinstabilityofobliqueLangmuir waveintolow‐frequencyelectromagneticshearAlfvenwaveandleft‐handedcircularlypolarized wave(LHCP)hasbeeninvestigatedinanelectron‐ionquantumplasmaimmersedinuniform external magnetic field. Incorporating the quantum effects due to electron spin, Fermi pressure and Bohmpotentialterm,thequantummagneto‐hydrodynamic(QMHD)modelhasbeenusedto investigatethelinearandnonlinearresponseoftheplasmaspeciesforthree‐wavecoupling interactionina quantummagneto‐plasmas.Nonlineardispersionrelationsandgrowthrateshave been derived analytically. It has been shown that the spin of electrons has considerable effect on the growth rate of parametric instability problem even when the external magnetic field B0 is below the quantum critical magnetic field strength BQ = 4.4138 ×1013 G. Finally,theparametricdecayinstabilityofobliqueLangmuirwaveintolow‐frequency electromagnetic shear Alfven wave and LHCP have also been investigated in high density (quantum) and low density (classical) magneto‐plasma environments. QMHD model has been used to find the linear and non‐linear response of the high density quantum magneto‐plasma, and to compare the (h → 0, Pe → Pte ) results with the low density classical plasma we have used classical limit in the results of QMHD model. Nonlinear dispersion relations and growth rates of the problem have been derived analytically. The growth rate both for quantum and classical magneto‐plasma environments has been plotted. The normalized growth rate as a function of number density in the high density degeneratemagneto‐plasmasincreasesexponentiallywhileinthelowdensityclassicalmagneto‐ plasmas it increases logarithmically.
