7-60 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Ali ibn Abdullah ibn Ishaq al-Ash’ari, on the authority of Al-Hassan ibn Mahboob, on the authority of Habib al-Sejestani, on the authority of Aba Abdullah as-Sadiq (MGB) that God’s Prophet (MGB) said,

“Fridays are days of worship. Thus, worship the Honorable the Exalted God. Saturdays are for the members of the Holy Household. Sundays are for their followers. Mondays are for the Umayyads. Tuesdays are easy days. Wednesdays are for the Abbasids and their victory. Thursdays are blessed days. For my followers its dawn is blessed.”
