John Penrice & R.B. Serjeant 
Dictionary and Glossary of the Koran [PDF ebook] 
In Arabic and English

John Penrice’s Dictionary and Glossary of the Kor-an first published almost a century ago, has withstood the test of time, and has been an aid to generations of Kor-an students. According to Islamic doctrine the Kor-an is the literal word of God, and it would be introduced by the phrase, "Qiil Allah ta’iilii, God the Exalted said", and when a passage has been recited aloud it will be said, "$adaq Allah al-‘Azim, God Almighty has truly spoken".
