Published: July 2022

Introduction.D-dimer is an important indicator, which reflects the activation of intravascular blood coagulation and fibrinolytic system. There are some data confirming that D-dimer is associated with stroke development in patients with atrial fibrillation. However, D-dimer is not included in modern stoke risk stratification scales in patients with atrial fibrillation.Aim— to analyze the data devoted to the role of D-dimer in stroke risk stratification in patients with atrial fibrillation.General findings.D-dimer, despite several limitations, could be used in clinical practice as an indicator that is associated with stroke development in patients with atrial fibrillation. D-dimer level estimation could help to decide whether to use anticoagulant treatment in patients with low risk of stroke development or in those patients with a single non-sex CHA2DS2-VASc score risk factor.

Authors: Khan Sobia 
Published: July 2022

Religious reform movements and religious economic movements differ greatly in their goals, organization, and manifestos. Reform movements emphasize the need to bring about change in society and to make individuals righteous in character. These worship for this purpose. Mention Meditation Use sermons and preaching. They have no restrictions on membership of the organization and their doors are open to everyone so that more and more people can benefit from them. In this way these movements emerge from below and create a public character within them. Do Leadership is not important in such organizations. The aim of reform movements is to reform society first. When society improves, political and economic changes will result automatically. Therefore, these movements are usually isolated from politics and do not like to confuse themselves in political disputes. Her argument is that in that case she will be in conflict with her political rivals and will not be able to do her job. On the contrary, we would call other movement’s reformist. Because they do not raise the slogan of revival or revolution, but they want to reform the present society without any fundamental change. They bring religion out of the past by adapting it to the modern age and try to eliminate the contradictions that exist between the basic religion and the modern requirements by adapting its teachings to the modern age.
Contemporary Applications of Istehsan in Zakat Related Issues
Authors: Ullah Minhaj , Hashmi Prof Dr. Mohyuddin 
Published: July 2022

Abstract

Zakat is one of the five pillars of Islam. Allah Almighty mentions it frequently in the Holy Quran. The Prophet (SAWS) also described its importance and virtue. He mentioned the punishments to be given in case of non-payment. The details of Zakat, i.e. the syllabus and the condition of passing the year on it, etc. show that Zakat is based on ease. The main purpose of Zakat is to help the needy and to distribute wealth fairly. Keeping in view these characteristics and aims of Zakat, the ancient jurists in their time inferred the issues which were in accordance with the conditions of that time and in accordance with the spirit of Sariah. However, due to the change of time and circumstances, some of the rules related to Zakat have come under attack on the purposes of Shariah and instead of ease in Zakat, a state of difficulty and hardship has started to arise. Therefore, these rulings need to be reviewed. Therefore, there is an urgent need for research work on this subject. In this article, the principle of Istishan has been applied to such issues and their ruling has been mentioned in the light of Istishan.

The research is comprises a survey study about the role of Pakistani media for promotion and observing inter-faith harmony among different religious communities in Pakistan. Media has a crucial part in maintain the social pulse especially on inter-faith harmony platform. Nationally and internationally, the wave of creditability is more recognized than the quickness of media so it is pertinent to understand to regularize the media of Pakistan that they should first recheck the news and incidents through the concerned professors of the area and the government officials then break a comprehensive report to stable the creditability of their channel and paint a positive image of Pakistan all over the world. It is also found that Pakistani media is not sufficiently covering the scholars of different religions other than Islam on social life topics and on harmonic points of their religions also.
