Challenging Ritual Piety: It's Time for Mosques to Become Epicentres of Earth's Salvation

Every week, millions of Muslims flock to mosques to perform Friday prayers. Thousands of religious study circles are held, producing strings of prayers and chants that rise to the heavens. However, when the congregation disperses, a contradictory scene is often left in the courtyard: plastic bottles strewn about, piles of leftover food boxes, and ablution water flowing to waste without any recycling. This reality provokes a fundamental challenge to our definition of piety. Does faith stop at the boundary of ritual prostration, while the environment around the house of worship is left to wither?

The momentum of the National Mosque Clean-Up Movement (GEBER MAS) must become a turning point to dismantle the wall separating ritual piety from socio-ecological piety. This movement is not merely an annual communal work agenda that ends when the Maghrib drum sounds. It is a spiritual manifesto to restore the mosque as a centre of climate-friendly civilisation. Yogyakarta, through a regional movement at the Jami’ Tajem Mosque in Maguwoharjo, Sleman, is attempting to offer a concrete model: marrying the local philosophy of Hamemayu Hayuning Bawana with environmental theology (eco-theology).

Eco-theology: Dismantling Half-Hearted Secularisation

All this time, we have been trapped in an acute, unconscious secularisation of thought. We separate the jurisprudence of worship from the jurisprudence of the environment (fiqh al-bi’ah). In fact, littering or allowing ablution water to be wasted is a betrayal of humanity’s mandate as khalifah fil ardh (stewards of the earth). The Prophet Muhammad explicitly stated that cleanliness is part of faith. Yet, why is its implementation at the grassroots level often limited to the interior aspects of the mosque, while external waste management is neglected?

Mosques can no longer be sterile ivory towers detached from the global environmental crisis. Through the integration of mosque administrator data into the Ministry of Religious Affairs’ Mosque Information System (SIMaS), the management structure of houses of worship must be reformed. Today’s mosque administrators are not only tasked with scheduling imams and preachers but must also act as environmental managers. An urgent first step is to build independent waste management systems and greywater recycling installations for ablution water to green the surrounding areas.

Cross-Sector Synergy, Not Just Ceremonial

Shifting the paradigm of hundreds of thousands of mosque administrators in Indonesia is clearly not a simple task. Therefore, the transition movement towards green mosques requires a strong anchor of collaboration. Synergy between the Regional Office of the Ministry of Religious Affairs of D.I.Y., the Indonesian Mosque Council (DMI), and philanthropic institutions like BAZNAS is an ideal roadmap. BAZNAS, for instance, can shift its orientation from consumptive aid to productive, environment-based assistance, such as procuring segregated waste bin infrastructure and productive plant seedlings for barren mosque yards.

When this movement is centred in Sleman as a starting point, the message echoes throughout the country: mosques must become the most vocal public education spaces voicing climate change issues. If Friday pulpits consistently begin to deliver sermons themed around the water crisis and waste emergency, the ecological awareness of the congregation will grow as a spiritual necessity, not merely submission to government regulations.

Towards a Future of Sustainable Mosques

The simultaneous action on Monday, 10 August 2026, is an initial manifesto. The real test is consistency after the ceremonial fanfare subsides. We yearn for a future where mosques in Indonesia become ecological sanctuaries—places where the air feels cool because of the lush trees in the yard, water is conserved through good eco-drainage systems, and energy is sourced from environmentally friendly solar panels.

Let us change our perspective. Caring for the cleanliness of the earth is no longer solely the task of environmental activists, but an absolute obligation of every human being who prostrates. Through GEBER MAS, we prove from within the mosque that Islam is a religion that nurtures life, heals the earth, and spreads mercy to all the worlds (rahmatan lil ’alamin). It is time to act, from the mosque for the future of the world. Wallahu’alam bishshawab.
