Sirajuddin Muhammad "Din" Syamsuddin (Arabic: مُحَمَّدُ سِرَاجِ ٱلدِّينِ شَمْسِ ٱلدِّينِ, romanized: Muḥammad Sirāj ad-Dīn Šams ad-Dīn, born in Sumbawa, West Nusa Tenggara, August 31, 1958 ), is an Indonesian politician and formerly the Chairman of Muhammadiyah for two terms from 2005 to 2010 and 2010 to 2015. His wife was named Fira Beranata, and has 3 children. He was entrusted to the Chairman of the Indonesian Ulema Council (Majelis Ulama Indonesia, MUI) Center, who previously served as Vice Chairman of the Indonesian Ulema Council replacing Center Dr (HC), KH. Sahal Mahfouz, who died on Friday, January 24, 2014.
As chairman of Muhammadiyah, he is often invited to attend a wide variety of international conferences with regard to the relationship between religion and peace. Most recently, for example, he was invited to the Vatican to give a public lecture about terrorism in the context of politics and ideology. He believes that terrorism is more relevant when associated with political issues than the issue of ideology. In line with that, he also was not happy when some Muslim groups used the label of Islam in performing terrorist actions. According to him, acts of terrorism in the name of Islam is very much detrimental to Muslims both at the internal level and Muslims on a global scale.
Din Shams is seen as a leader of Muslims not only because he is the Chairman of Muhammadiyah, but even more so because of his ability to engage in dialogue with all elements of both faiths among Muslims, as well as with other religious communities.
