7-62 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Sahl ibn Zyad al-Adamy, on the authority of Abul Hassan Amr ibn Sufyan al-Gorjany who linked it up through a chain of narrators to Aba Abdullah as-Sadiq (MGB), “As-Sadiq (MGB) asked one of his friends, ‘O so and so! Why you did you not go out today?’ He replied, ‘May I be your ransom! Because it is Sunday.’ The Imam (MGB) asked him, ‘So what? What is wrong with Sunday?’ The man said, ‘It has been narrated on the authority of God’s Prophet (MGB) to have said, ‘Beware of Sundays as they are as sharp as a sword!’ The Imam (MGB) said, ‘No that is not so. They have lied about the Prophet (MGB) having said that since Ahad which means Sunday is one of the Names of the Honorable the Exalted God.’ The man said, ‘May I be your ransom! What about Mondays?’ The Imam (MGB) said, ‘It has been named after those two.’ The man said, ‘But Monday was known as Monday before those two.’ Abu Abdullah as-Sadiq (MGB) told him, ‘Once you are told something try to understand it! Indeed the Blessed the Sublime God already knew the day on which He would appoint His Prophet (MGB), and the day on which the Prophet’s Trustee (MGB) would be oppressed. Thus, it was named after those two.’ The man said, ‘What about Tuesdays?’ The Imam (MGB) said, ‘God created Hell on a Tuesday as the Sublime God says, ‘(It will be said,) ‘Depart ye to that which ye used to reject as false! Depart ye to a Shadow (of smoke ascending) in three columns, (Which yields) no shade of coolness, and is of no use against the fierce Blaze.’”The man said, ‘What about Wednesdays?’ The Imam (MGB) said, ‘The four pillars of Fire were made on a Wednesday.’The man said, ‘What about Thursdays?’ The Imam (MGB) said, ‘God created Paradise on a Thursday.’The man said, ‘What about Fridays?’ The Imam (MGB) said, ‘The Honorable the Exalted God gathered the people together on Fridays to acknowledge our Mastery.’The man said, ‘What about Saturdays?’ The Imam (MGB) said, ‘It was on a Saturday that the angels attended to their Lord and realized that He has always been the One.’”
