Bank Syariah Indonesia, as the largest Islamic bank in Indonesia, plays an important role in driving the country's economic growth. In addition, the bank is also expected to improve its social services to the community through various aspects, including education, health, environment and renewable energy. In conclusion, Monzer Kahf's views on Islamic banking are highly relevant to the development of Islamic banking in Indonesia.
