21-8 Ahmad ibn al-Hassan al-Qat’tan narrated that Ahmad ibn Yahya ibn Zakaria al-Qat’tan quoted Bakr ibn Abdullah ibn Habib, on the authority of Tamim ibn Buhlool, on the authority of Abu Muawiyah, on the authority of Isma’il ibn Mihran that he had heard Ja’far ibn Muhammad as-Sadiq (MGB)say, “I swear by God that God has not placed a burden on His servants more than they can bear. He has only required that they pray five times each day and night; has established only twenty-five Dirhams of alms-tax for each one-thousand Dirhams; has only required them to fast for thirty days during a year; and has only required them to go on the Hajj pilgrimage once in their lifetime.”The compiler of the book - may God be pleased with him - said, “The Shiites and their wise men consider Ramazan as never being less than thirty days. The narrations which have been written in this chapter are in agreement with the Quran but against the public opinion (that sometimes the month of Ramazan may be less than thirty days). Those people with little faith in the Shiites who have maintained that Ramazan is thirty days every now and then, and twenty-nine days every now and then, have resorted to the concealment of faith. They have supported the general viewpoint of the public. There is no power nor any strength but in God.”
