Almighty sent his chosen prophets to every Ummah to teach them the lesson of goodness and to avoid evil. The purposes of the Prophet (peace and blessings of Allah be upon him) were reform processes: to teach and guide, and pushed the people to Almighty Allah. According to the narrative in Islamic law, everyone's either Muslim or non-Muslim, relative or/neighbor has determined the right to live things. And good conduct is that because Abdullah bin Mubarak said That is, "Meeting old habits, doing righteousness, and forbidding people to hurt you". If human behavior is good then its own life will also pass through fortune and joy, and it will also be the mercy and chain of things for others. Collective relations, interacting with the recipients, and the Family system, is proven to be a source of intelligence. The result of the happy moral is Reality and Heaven of Arman al-Rahman, and the fulfillment of the Prophecy is the wrath of Lord Koran and the Fire of Hell.

In this thesis, we discuss the dynamical stability of charged compact objects with the help of some mathematical models. For this purpose, we have selected three different models of charged compact objects to discuss the possible occurrence of cracking under different conditions. In first selected model, we discuss charged anisotropic compact objects with a linear equation of state. In second model, we study anisotropic charged compact object PSR J1614-2230 in quadratic regime, while in third model, we study charged compact stars corresponding to embedded class one metric with perfect inner fluid distribution. We investigate the impact of electromagnetic field on the stability regions of charged self-gravitating compact objects by using the concept of cracking. For this, we have applied local density perturbation scheme to the hydrostatic equilibrium equation as well as on physical parameters involved in the model. In particular, we have examined the cracking of charged compact objects (a) PSR J1614-2230, PSR J1903+327, Vela X-1, SMC X-1 and Cen X-3 with linear equation of state (b) PSR J1614-2230 with quadratic equation of state (c) Her X-1, PSR 1937+21, PSR J1614-2230, PSR J0348+0432 and RX J1856-37 corresponding to embedded class one metric. We conclude that these objects exhibit cracking and stability regions decreases with the increase of charge. We also extend two conventional polytropic equations of state to generalized polytropic equations of state for spherical and cylindrical symmetries in the context of general relativity. For this purpose, we formulate the general framework to discuss the physical properties of spherical and cylindrical polytropes with charged anisotropic inner fluid distribution under conformally flat condition. We investigate the stability of generalized polytropic models through Tolman-mass and Whittaker formula for spherical and cylindrical symmetries respectively. We also discuss the possible occurrence of cracking in charged anisotropic polytropes developed under the assumption of generalized polytropic equation of state in two different ways (i) by carrying out local density perturbation under conformally flat condition (ii) by parametric perturbations. We conclud that one of the generalized polytropic equations of state results into a physically viable model and cracking appears for a specific range of density and model parameters.
