in the Indian subcontinent. According to the Legend of Cheraman Perumals, the first Indian mosque was built in 624 CE at Kodungallur in present-day Kerala with the mandate of the last the ruler (the Cheraman Perumal) of Chera dynasty, who converted to Islam during the lifetime of the Islamic prophet Muhammad (c. 570–632). According to Qissat Shakarwati Farmad, the Masjids at Kodungallur, Kollam, Madayi, Barkur, Mangalore, Kasaragod, Kannur, Dharmadam, Panthalayini, and Chaliyam, were built during the era of Malik Dinar, and they are among the oldest Masjids in the Indian subcontinent. It is believed that Malik Dinar died at Thalangara in Kasaragod town. The first Indian mosque, Cheraman Juma Mosque, is thought to have been built in 629 CE by Malik Deenar although some historians say the first mosque was in Gujarat in between 610 and 623 CE. In Malabar, the Mappilas may have been the first community to convert to Islam. Intensive missionary activities were carried out along the coast and many other natives embraced Islam. According to legend, two travellers from India, Moulai Abdullah (formerly known as Baalam Nath) and Maulai Nuruddin (Rupnath), went to the court of Imam Mustansir (427–487 AH)/(1036-1094 CE) and were so impressed that they converted to Islam and came back to preach in India in 467 AH/1073 CE. Moulai Ahmed was their companion. Abadullah was the first Wali-ul-Hind (saint of India). He came across a married couple named Kaka Akela and Kaki Akela who became his first converts in the Taiyabi (Bohra) community. Arab–Indian interactions There is much historical evidence to show that Arabs and Muslims interacted with Indians from the very early days of Islam or even before the arrival of Islam in Arab regions. Arab traders transmitted the numeral system developed by Indians to the Middle East and Europe. Many Sanskrit books were translated into Arabic as early as the 8th century. George Saliba in his book "Islamic Science and the Making of the European Renaissance", writes that "some major Sanskrit texts began to be translated during the reign of the second Abbasid caliph al-Mansur (r. 754–775), if not before; some texts on logic even before that, and it has been generally accepted that the Persian and Sanskrit texts, few as they were, were indeed the first to be translated."
