At the moment, you can't read JIHADI: A LOVE STORY -- it's making a national tour of elite slush piles -- but when you do, one of the things I hope you'll notice is that the protagonist's manuscript begins and ends with a supplication to God. In Islam, we call that kind of prayer dua.
And your Lord says: "Call on Me; I will answer your (dua): —Qur'an, Sura 40 (Ghafir), verse 60
The Qur'an itself is an answered dua. In Sura 1 (below), which opens the Holy Book, God Almighty shares the Seven Oft-Repeated Verses, which form the core of practice and observance in Islam. These seven verses constitute a plea from humankind for guidance from Almighty God. Suras 2-114 (constituting the rest of the Qur'an) constitute the answer to that dua! All praise to God Almighty!
