Planting Trees as an Investment for the Hereafter: Integrating the Prophet's Hadith and Scientific Data on the Number of Trees in the World into Sustainable Environmental Education

This study aims to examine the ecological principles in the hadiths of the Prophet Muhammad and integrate them with the latest scientific data on global ecosystem conditions, particularly the number of trees on earth, to develop a sustainable environmental education model based on Islamic values. This study employs a qualitative approach, utilizing a library research method through content analysis of ecological hadiths, hadith interpretation literature, and modern scientific publications on forestry and climate change. The results show that the Prophet's hadiths on tree planting, the prohibition of destroying nature, and the mandate of humans as caliphs of the earth are strongly consistent with modern scientific principles regarding the role of trees in maintaining carbon balance and biodiversity. This normative-spiritual and scientific integration gives rise to the paradigm of eco-Islamic pedagogy, an educational approach that fosters faith-based ecological awareness while being grounded in scientific evidence. This model emphasizes thematic learning, project-based activities, and community involvement to shape the character of students who are faithful, knowledgeable, and ecologically conscious. This study concludes that environmental conservation is an expression of faith and moral responsibility in Islam. Future research recommendations include the need to develop the implementation of eco-Islamic pedagogy in Islamic educational institutions through adaptive curricula and interdisciplinary collaboration between scholars, educators, and environmental scientists.
