Quran 1:1-7 (al-Fatiha)

Kristina Nelson's study of Quranic recitation practice describes al-Fatiha as very likely the most repeated text in human religious life by sheer volume of daily recitation. Islamic law requires it in every rakah, every unit of the five daily prayers, so a practicing Muslim who prays the minimum obligatory cycles recites these seven verses at least seventeen times a day, and considerably more with voluntary prayers added. Multiplied across roughly two billion Muslims worldwide, the arithmetic makes al-Fatiha a serious candidate for the single most recited passage of any scripture anywhere, ahead of any single verse from a tradition where recitation is occasional rather than built structurally into obligatory worship.

Nelson's work also describes how recitation itself, tajwid, the disciplined art of pronouncing and intoning the Arabic text correctly, is taught and judged as a skill distinct from ordinary reading, with competitions, trained reciters and regional styles of its own. Al-Fatiha's place at the opening of the Quran and at the center of every prayer cycle makes it the passage every reciter learns first and performs most, so mastery of it functions as something like a rite of passage into the recitation tradition itself, well before a student moves on to longer suras.
