Nostra Aetate.
3. The Church regards with esteem also the Moslems. They adore the one God,  living and subsisting in Himself; merciful and all- powerful, the Creator of  heaven and earth,(5) who has spoken to men; they take pains to submit  wholeheartedly to even His inscrutable decrees, just as Abraham, with whom the  faith of Islam takes pleasure in linking itself, submitted to God. Though they  do not acknowledge Jesus as God, they revere Him as a prophet. They also honor  Mary, His virgin Mother; at times they even call on her with devotion. In  addition, they await the day of judgment when God will render their deserts to  all those who have been raised up from the dead. Finally, they value the moral  life and worship God especially through prayer, almsgiving and fasting.     
 
Since in the course of centuries not a few quarrels and hostilities have  arisen between Christians and Moslems, this sacred synod urges all to forget the  past and to work sincerely for mutual understanding and to preserve as well as  to promote together for the benefit of all mankind social justice and moral  welfare, as well as peace and freedom.
