I heard the Prophet ﷺ say, "None of you should fast on Friday unless he fasts a day before it or a day after it."
سمعت النبي ﷺ يقول: لا يصوم أحدكم يوم الجمعة إلا يوما قبله أو بعده.
Bukhari narrated it in the Book of Fasting (1985), and Muslim in the Book of Fasting (1144:147), both of them via Amash, who said, Abu Salih narrated to us, from Abu Hurairah, and he mentioned it.
