بیزارچھپکلیاں
سادہ لو ح پتنگے نگلتی چھپکلیاں
جگہ جگہ زہر اگلتی ہوئی
سیاہ رات میں بے خبر رینگتی چلی جاتی ہیں
خود کو آزاد سمجھ رہی ہیں
شب کی سولی پہ لٹکتی یہ بیزار مخلوق
اپنے جسموں کی نمائش سے بے پروا
مکاری کے نقاب پہنے
آنکھوں میں آنچلوں کے رنگ لہراتے ہوئے
جنھیں محافظ سمجھ کر بانہوں میں جھول رہی ہیں
انھیں خبر نہیں
وہ ہوس کے زہریلے سانپ ہیں
جو ان کے حسن کا سارا خزانہ ایک ہی سانس میں نگل جائیں گے
ان کی سادگی نوچ لیں گے
زندگی نوچ لیں گے
There are two main sources of Islam, one is the Book of Allah and the other is the Sunnah and Sira of the Prophet (peace be upon him). The Qur'an is the final collection of 23 years of divine revelation revealed to the Holy Prophet (PBUH) whose literal and spiritual preservation was undertaken by Allah Almighty Himself. Therefore, the Qur'an is the only book in the world which has one letter, one action and one line in its original state just as it was revealed to the pure heart of the Holy Prophet (sws) and the Holy Prophet (sws). The Prophet (peace and blessings of Allaah be upon him) told the Sahaabah. That is why the greatest truth of Islam, the book is the living Qur'an. The second major basis of the reality of Islam is the pure Sira and Sunnah of the Prophet of Humanity, the Servant of the Universe. Like the Qur'an al-Hakim, every moment, every day and every angle of the life of the author of the Qur'an is in front of everyone like an open book with all its mysteries. Even in front of one's own and in front of others. A da’if hadith is a hadith which does not fulfil the conditions of the sahih or hassan hadith.
Ruling: There is a difference of opinion between the ‘ulema on the ruling on acting upon weak hadiths. The reliable opinion is that weak hadiths can be acted upon for virtuous supererogatory deeds (fada’il al a’mal), for religious exhortation, and stories, and similar things that are not connected to legal rulings and tenants of belief.
Keywords: Hadith, Hadith e Da’eef, Derivation of Ahkaam, Jurists, Different opinions.
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.

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.
