Inside the Lala Mustafa Paşa Mosque: young children during a Koranic lesson,

Regarding Koranic lessons.
Koran (Quran) literally means ‘the recitation’. To learn this recitation of the Holy Book, and (for the best pupils) to recite the whole scripture by heart is the essence of these lessons. As the Koran is written in Arabic – a language totally different from Turkish, even if some Turkish vocabulary derives from Arabic – this is not a small challenge. Also, apart from the recitation, a good teacher will have to explain the meaning of the Holy texts too.
