all three books have survived and have been published several times. Islamic tradition also holds that translations were made for Emperor Negus of Abyssinia and Byzantine Emperor Heraclius, as both received letters by Muhammad containing verses from the Quran. In early centuries, the permissibility of translations was not an issue, but whether one could use translations in prayer. In 1936, translations in 102 languages were known. In 2010, the Hürriyet Daily News and Economic Review reported that the Quran was presented in 112 languages at the 18th International Quran Exhibition in Tehran. Robert of Ketton's 1143 translation of the Quran for Peter the Venerable, Lex Mahumet pseudoprophete, was the first into a Western language (Latin).

The oldest Gurmukhi translation of the Quran Sharif has been found in village Lande of Moga district of Punjab which was printed in 1911.
