Stunning is the process of rendering animals immobile or unconscious, with or without killing the animal, when or immediately prior to slaughtering them for food. In modern slaughterhouses a variety of stunning methods are used on livestock. Methods include: Electrical stunning, Gas stunning, Percussive stunning. There are three opinions of Islamic scholars about stunning. Those scholars; who do not allow stunning at all; are of the view that the method of rendering animals unconscious before slaughter is against the shairah method and Sunnah, and it is Makrooh e Teḥreemi. Before slaughtering, if an animal died due to stunning, then that animal is carcass and is not allowed to be eaten. But, if before slaughter, ḥayat e Mustaqirrah is present in animal and it is slaughtered in that condition then it is permissible to eat it. Certain scholars allow stunning in certain situations with some terms and conditions. The decisions of Mjam e Faqhiyyah of modern age are also based on conditional permission. Moreover, Mufti Muḥammad Taqi Usmani, Dr. Wahabah  Zoḥaili and Abdul Aziz Bin Baaz agree with conditional permission, while some other scholars allow all types of stunning without any condition; Mufti Muḥammad Abduho and his pupil Allamah Rasheed Raza Miṣri agree with later opinion.

Some Aspects of Modified Gauss Bonnet Gravity

This thesis deals with some cosmic aspects in the context of modified Gauss-Bonnet gravity. Firstly, we explore static spherically symmetric wormhole solutions in galactic halo region as well as using conformal Killing vectors technique. The effective energymomentum tensor leads to the violation of energy conditions while normal matter satisfies these conditions. We use Navarro-Frenk-White energy density profile to examine possible existence of traversable wormholes in galactic halo region. We find physically acceptable wormhole solutions threaded by normal matter for all values of r. We also investigate stability of the resulting wormhole solutions. For conformally symmetric traversable wormholes, it is found that all shape functions satisfy flaringout condition except phantom case with non-static conformal symmetry. Secondly, we study the dynamics of self-gravitating objects for spherical and axial systems. We construct structure scalars through orthogonal splitting of the Riemann tensor and deduce a complete set of equations governing the evolution of dissipative anisotropic fluid in terms of these scalars. In spherically symmetric system, we investigate some particular fluid models according to various dynamical conditions and find that our results are consistent with general relativity for constant f(G) model. Any other choice of the model leads to irregular distribution of dark energy and deviates from general relativity. We also explore different causes of density inhomogeneity which turns out to be a necessary condition in the presence of dark sources. In axially symmetric system with shear, it is found that dark sources affect thermodynamics of the system, evolution of kinematical quantities as well as density inhomogeneity. For the shear-free case, we study both non-geodesic as well as geodesicfluids with and without dissipation. The non-geodesic (non-dissipative) fluid gives inhomogeneous expansion while geodesic fluid leads the system either to vorticityfree or expansion-free. The vorticity-free non-dissipative geodesic fluid reduces the axial system to FRW model with homogeneous distribution of dark sources while expansion-free geodesic fluid does not exist even in the presence of dark sources.
