Michael Sells explains the mosque architecture by indicating the rounded dome and a tower built for calling the prayer, known as Minaret. A person who stands on the tower and chants the call to prayer called Mu'adhdhin. Also, Sells provides a guide on how to pronounce both Sunni and Shia Adhan ( a call to prayer). In a recited circle, children's began to educate Quran while quoting short sura's led by Shaykh. Tajwid creates an elision between the words and teaches how to draw the vowel sound.
