Thajuddin, formerly known as the Tamil King Cheraman Perumal (lit. "Great lord of the Cheras"),[1][2][3] played a significant role in history as the first Indian monarch to embrace Islam. After his conversion, the Siddhars gave him the title Makkahvukkupona Perumal (lit. "Emperor who went to Makkah").[4][5] His conversion tale is steeped in intriguing events, with a pivotal moment revolving around the legendary splitting of the moon.[6][7]
