It was narrated from Abu Hurayrah that the Prophet (peace and blessings of Allaah be upon him) said: “Do not single out the night of Friday for qiyaam al-layl, and do not single out the day of Friday for fasting, unless that is part of the habitual fasting of any one of you.”
(Narrated by Muslim, 1144).
So, along with these virtues and acts of worship, the Prophet (peace and blessings of Allaah be upon him) forbade singling out Friday for fasting, or singling out the night of Friday for doing acts of worship that are not narrated in sharee’ah.
