آیتِ کریمہ يَاأَيُّهَا الَّذِينَ آمَنُوا لَا تَقُولُوا رَاعِنَا وَقُولُوا انْظُرْنَا سےحجیتِ سدُالذرائع پر ابنِ حزم کےمعارضہ کا تجزیاتی مطالعہ An Analytical Study of the Ibn-e-Hazam’s Objections to Authenticity of the Sadd-o-Zaree'ah

As well as per Shariah, it is admissible and some of the time even mandatory to save the devotees from the activities that might lead them towards the prohibited exercises. Consequently, the decision of denial from these kinds of exercises is called Sadd-e-Zaree'a. This is the guideline derived from the Quran and Sunnah. As Almighty Allah prohibited the devotees to say 'Raina' because this word was utilized by Jews purposely in an off-base way with underhanded aims, while, Muslims introduced their solicitations by this equivalent word in the most elevated court of The Holy Prophet (harmony and gifts arrive) for looking for effortlessness and unwinding in their concerned issues. As in Quran: O People who Believe, don't tell (the Prophet Mohammed-harmony and gifts arrive), "Raina (Be accommodating towards us)" however say, "Unzurna (Look leniently upon us)", and listen mindfully in any case. [Baqarah 2:104]. (To disregard the Holy Prophet - harmony and endowments arrive - is impiety.) Ibn Hazm in his famous book Al-Aḥkām Fī ūṣūl Al-Aḥkām has objected to the mentioned verse from which jurists have taken the argument of Sadd-e-Zaree'a. Because the Zahiri school of thought is based on the appearance of the text (Quran o Hadees). This is why Ibn Hazm Zahiri denies it (the source of Shariah), and proves that accepting the source of Shariah is an increase in religion which is in itself illegitimate as well as the opposition of the Prophet (peace and blessings of Allah be upon him). There is also the addition of items by their thoughts in Shariah. In the above article, an analytical study of the objections of Allama Ibn Hazm will be presented, explaining the sources and the arguments as to whether or not their source is Shariah.

Solitary Structures in Space Plasmas With Non-Maxwellian Electron Distributions

The objective of this study is to investigate linear and nonlinear propagation of kinetic Alfven waves (KAWs) and coupled kinetic Alfven-acoustic (CKAA) waves in non Maxwellian plasmas. Theoretical frame works that employed Maxwellian, kappa and Cairns distributions could not explain observations of flat top and spiky distributions. Generalized (?, ?) distribution function encompasses both low energy and high energy parts of the observed velocity distributions and provides good quantitative fits of the observed data. KAWs has been observed to play an important role in acceleration and heating of plasma particles in space and laboratory plasmas. The study is carried out by using two-potential theory and solitary structures are obtained by applying Sagdeev potential approach. A comprehensive study has been carried out to ascertain how the formation of compressive and rarefactive solitary structures of KAWs and CKAA waves depend on the low and high energy parts of the electron distribution function. It has been shown that out results agree well with Fast and Freja observations of the nonlinear KAWs. An important feature of our study is the formation of rarefactive solitary structures. The analysis of compressive and rarefactive solitary structures of CKAA waves reveals that flat top at low energies of the electron distribution are responsible for the formation of compressive solitary structures whereas the spikes at low energies allow the formation of both compressive and rarefactive solitary structures. We have extended our investigations of CKAA waves for electron-positron-ion (e-p-i) plasmas, particularly highlighting the role of nonthermal electrons and positrons following generalized (?, ?) distribution. The significance of this study is to emphasize the existence of density dip solitons for spiky distribution at low energy. The relevance of the study presented in this thesis with reference to astrophysical, space and laboratory plasmas has also been discussed.
