Buddhism and Hinduism religions had been prevalent in Kashmir at various points of time. Islam started making inroads in the 12th and 13th centuries. The earliest copy of Quran in Kashmir dates back to 1237 AD and was calligraphed by Fateh Ullah Kashmiri who is believed to be a then Kashmiri Islamic scholar. The first Muslim missionary in Kashmir was Syed Sharaf-ud-Din Abdur Rahman Suhrawardi popularly known as Bulbul Shah to common masses. He was an extensively travelled preacher and came to Kashmir during the reign of Raja Suhadeva (1301–20). Impressed by Bulbul Shah's simplicity and noble character, King Rinchan Shah the ruler of Kashmir accepted Islam and came to be known as Sultan Saddrudin Shah. He was the first Muslim ruler of Kashmir.
