O you who acknowledge, if the contact prayer is called to on the day of assembly, then you shall hasten towards the remembrance of God, and cease all selling. This is better for you, if you only knew.

[62:9] See 16:97. There is a question regarding the implication of the Yawm al Jumua (the day of congregation). The traditional understanding consider it a reference to the 5th day of the week, that is, Friday. However, the Arabic word could be a description of any day picked by a group of people for assembly prayer, for a public event with political, social and spiritual purposes. If Arabs had another word for Friday (such as, Aruba) during the era of Quranic revelation, then we should understand this day to be any day chosen by a group of people in a particular location to meet and pray together. This understanding might be supported by the condition of calling or inviting people to the prayer. For an already known day and time, such as Friday noon, such an invitation or announcement loses its meaning. 20:114.We should also note that the day set for congregational prayer is not the day of complete rest, such as Sabbath. For researchers, I recommend Studies in Islamic History and Institutions by Shelomo Dov Goitein, 1966.
