Maslakhatul Ainiyah, Faqihatin — Sun, 07 Jul 2024 00:00:00 +0800

Communication is a fundamental part of human life and is very important in the family, where parents act as the primary educators. Many parents work, resulting in reduced communication with their children. Communication within the family aims to strengthen social relationships and influence the development of the child's personality. Effective communication includes feelings of togetherness, mutual understanding, and emotional involvement. This research aims to describe the effectiveness of communication in shaping the personality of young children (early childhood) in the village of Kramat, Mengare Bungah, Gresik. Using a qualitative study design through observation and interview, we found that family communication is very important in influencing children's behavior. The more effective the communication between parents and children, the more the child's intrapersonal intelligence develops. Open communication between children and parents builds a positive self-concept in children, making them feel accepted and confident in making their own choices.

Harmonizing Islamic Quantum in Islamic Education: An Islamic Perspective Through the Lens Of Nidhal Guessoum's Philosophy

Shobihatul Fitroh Noviyanti, Ririn Inayatul Mahfudloh, Moh Romzi — Sun, 07 Jul 2024 00:00:00 +0800

This article aims to discuss explore Nidhal Guessoum's perspective on the relationship between Islam and modern science, utilizing library research methods and a qualitative approach. The primary focus is on the views of Muslim thinkers regarding the cosmology of classical Islamic philosophy, scientific interpretations, traditionalism, and modern science. Guessoum proposes a theistic Islamic cosmological view, in which cosmology serves as a framework for monotheism. While cosmology cannot fully encompass science, Guessoum argues that a Muslim must study science while maintaining belief in the existence of God. He emphasizes that Islamic cosmology is not merely a scientific explanation but an integration of religion and modern science. Guessoum's quantum approach is based on three principles: conceptual integration between religion and science, interdisciplinary methods to understand natural and religious phenomena, and critical thinking to evaluate diverse views. He highlights the importance of Muslim identity in the study of science, which allows a Muslim to uphold their faith. Guessoum acknowledges the weaknesses in the traditional approach to Islamic cosmology and offers a more coherent and integrative alternative. His thinking offers a new perspective that combines Islamic cosmology with scientific principles, offering a framework for understanding how religion and science can coexist harmoniously.

Ferryani Krisnawati — Sun, 07 Jul 2024 00:00:00 +0800

Inheritance law in Indonesia is categorized into three distinct systems: Islamic inheritance law, civil inheritance law, and customary inheritance law. Each system varies in terms of heirs, distribution methods, and legal bases. Inheritance law is a component of civil law and a subset of family law. This research examines inheritance laws under the Civil Code and Islamic law, highlighting the differences between the two systems. Islamic inheritance law, as outlined in Surah An-Nissa, clearly defines the portions for heirs, whereas the Civil Code bases inheritance distribution on the number of heirs. This discrepancy in distribution forms the core of the study. The research employs a Normative Juridical approach, relying on primary legal sources to examine theories, concepts, legal principles, and statutory regulations relevant to the study. The research specifications are analytical descriptions.
