This document analyzes the number of rakats recited by the Prophet Muhammad in different prayers based on hadith sources. It summarizes that according to reliable hadith sources, the Prophet would recite 8 rakats for some mandatory prayers. However, other hadith mention up to 20 rakats for some prayers. The author conducted a study to analyze the authenticity of hadith claiming more than 8 or 20 rakats and determined they were weak based on their isnad (chain of transmission).
