We have one of the oldest and India's first masjid called the Cheraman Jama Masjid exists at Kodungaloor in Kerala. As inscribed on the masjid's stone-plate, (where this writer has been after the historic Tsunami in 2004), it was built about 1400 years ago in 9 Hijra or 629 CE). Kodungaloor was the capital of the kings of Kerala, and in 622-628 CE (Hijra 2 to 9) the ruler was a great savant, by the name of Cheraman Perumal Bhaskara Ravi Varma. In those days, the seniormost of the rulers of Kerala was called as Cheraman Perumal.
