<p>Fauzan, S.Ag.,M.H<br />UIN Fatmawati Sukarno Bengkulu, Indonesia <br />Editor in Chief, Madania: Jurnal Kajian Keislaman</p><p>Dear Dr. Fauzan.<br />We are pleased to submit our manuscript entitled “Spatial Finance Exploration on Hajj Funds Sustainability Growth: Evidence from Indonesian Archipelagic“ to Madania: Jurnal Kajian Keislaman.</p><p>This present study offers a novelty in exploring the spatial finance approach to measuring factors affecting the Hajj fund Sustainability Growth. Because of the long waiting time for prospective pilgrims in Indonesia, the Hajj fund is not only applicable as financing for prospective pilgrims but also as a driver of the economic sector and an eternal source of financing funds for Islamic banks. This study also offers the most essence, namely the method of mapping the spillover effect on areas suspected of having the potential to become the centre of spillover. The empirics in this study prove that the Islamic bank office network and religiosity level had a spatial influence on Hajj fund growth. Meanwhile, the increase in COVID-19 cases does not affect hajj funds growth. Besides, the spatial mapping predicts that two provinces have a strong potential to give spillover effects in influencing the surrounding regions. The governance and bankers need to consider spatial aspects to maximize the region's potential in encouraging an increase in the number of areas that can have a spillover effect on their neighbouring regions. So, it can increase the hajj fund's sustainability growth.</p><p>We declare that this manuscript has not been published elsewhere and is not under review by another journal. All authors have approved the manuscript and have agreed to its submission Madania: Jurnal Kajian Keislaman.</p><p>Thank you for your consideration. We look forward to hearing from you at your earliest convenience. Please address all correspondence to: acehasans.uinjkt@gmail.com.</p><p>Sincerely,</p><p>TB. Ace Hasan Syadzily</p>
