١٢-٦٣ حدثنا أبي رضي الله عنه قال: حدثنا سعد بن عبد الله، عن أحمد بن أبي عبد الله البرقي، عن أبيه، عن حماد بن عيسى، عن الصباح بن سيابة، عن أبي جعفر عليه السلام قال: إن الله عز وجل خلق الشهور اثني عشر شهرا وهي ثلاثمائة وستون يوما، فحجر منها ستة أيام خلق فيها السماوات والارضين، فمن ثم تقاصرت الشهور
12-63 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Ahmad ibn Aba Abdullah al-Barqy, on the authority of his father, on the authority of Hammad ibn Isa, on the authority of Al-Sabah ibn Siabat that Abi Ja’far al-Baqir (MGB) said, “The Honorable the Exalted God created the twelve months which are three-hundred and sixty days. However, the six days during which the heavens and the two Earths were created were subtracted. Therefore, some (lunar) months are less than thirty days.”
