Bismillah:

Abu Hurayrah رضي الله عنه said:

The Prophet صلى الله عليه وسلم said:

''Do not single out the night of Friday from other nights for praying qiyaam, and do not single out Friday from other days for fasting, unless it is part of a fast that one of you regularly observes.''

Takhreej:

{ Imam Muslim in his Saheeh #1144 }

Imaam Al Nawaawi رجمه الله commented:

This hadeeth clearly indicates that it is forbidden to single out the night of Friday from other nights for praying, and to single out that day for fasting. It is unanimously agreed (among the scholars) that this is makrooh.

Imaam Abdul Azeez bin Baaz رحمه الله commented:

If the Day of ‘Arafat happens to fall on a Friday and a Muslim fasts on this day only, there is nothing wrong with that, because he is fasting because it is the Day of ‘Arafat, not because it is a Friday. Similarly, if he has days to make up from Ramadan and he has no free time except on Friday, then there is no sin on him if he singles it out; that is because it is a day off for him. Similarly if the day of ‘Ashoora’ happens to fall on a Friday, there is no sin on him if he singles it out for fasting, because he is fasting because it is ‘Ashoora’ not because it is Friday. Hence the Prophet صلى الله عليه وسلم said: “Do not single out Friday for fasting, and do not single out the night of Friday for praying qiyaam.” So this hadeeth refers to singling it out, i.e., when a person does that just because it is Friday or the night of Friday.
