What is the best day of the week for worship in the mosque after Friday, Saturday or Sunday?

There is no additional virtue for worship on Saturdays and Sundays for Muslims; they are equal in worship because there is no legitimate proof that singles them out with a special virtue. It should be noted that these are days of celebration for Jews and Christians. Residence in non-Muslim lands is not permissible except for one who can observe the rituals of his religion and is secure from temptation.
