IT IS MAKROOH TO SINGLE OUT FASTING ON FRIDAY:-
Narrated Muhammad bin `Abbas:
I asked Jabir “Did the Prophet (PEACE BE UPON HIM) forbid fasting on Fridays?” He replied, “Yes.” (Other narrators added, “If he intends to fast only that day.”)

Muhammad b. ‘Abbas b. Ja’far reported:
I asked Jabir b. ‘Abdullah (Allah be pleased with both of them) as he was circumambulating the House (Ka’ba) whether the Messenger of Allah (may peace be upon him) had forbidden the fasting on Friday, whereupon he said: Yes, by the Lord of this House.
SAHIH MUSLIM (Book 6, Hadith 2543)
Abu Huraira (Allah be pleased with him) reported the Apostle of Allah (may peace be upon him) as saying: None among you should observe fast on Friday, but only that he observes fast before it and after it.
SAHIH MUSLIM (Book 6, Hadith 2545)
Abu Huraira (Allah be pleased with him) reported Allah’s Apostle (may peace be upon him) as saying:Do not single out the night (preceding) Friday among the nights for prayer and do not single out Friday among days for fasting but only when anyone among you is accustomed to fast (on dates) which coincide with this day (Friday).
SAHIH MUSLIM (Book 6, Hadith 2546)
Narrated Abu Aiyub from Juwairiya bint Al-Harith:
The Prophet (PEACE BE UPON HIM) visited her (Juwairiya) on a Friday and she was fasting. He asked her, “Did you fast yesterday?” She said, “No.” He said, “Do you intend to fast tomorrow?” She said, “No.” He said, “Then break your fast.” Through another series of narrators, Abu Aiyub is reported to have said, “He ordered her and she broke her fast.”
SAHIH BUKHARI (Vol. 3, Book 31, Hadith 207)
Abu Hurairah narrated that :
the Messenger of Allah said: “None of you should fast on Friday unless he fasts before it, or he fasts after it.” (Sahih)
SUNAN TIRMIDHI (Vol. 2, Book 3, Hadith 743)
Ibn Qudaamah said:
“It is makrooh to single out the day of Friday for fasting, unless that coincides with a fast which one usually observes, such as a person who fasts alternate days, and a day that he fasts coincides with Friday, or a person who has the habit of fasting on the first or last day of the month, or the middle day of the month.”
(Al-Mughni, Vol. 3, Page. 53)
“Our companions (i.e. the Shaafa’is) said: it is makrooh to single out the day of Friday for fasting, but if one joins it with the day before or the day after, or it coincides with a day which he habitually fasts, or he vowed to fast the day that his sick loved one was cured, or the day So and so returns, and that day happens to be a Friday, then it is not makrooh
(Al-Majmoo’ Sharh al-Muhadhdhab, Vol. 6, Page. 479)
Shaykh al-Islam (may Allaah have mercy on him) said:
“The Sunnah says that it is makrooh to single out Rajab for fasting, and it is makrooh to single out Friday (for fasting).”
(Al-Fataawa al-Kubra, Vol. 6, Page. 180)
Shaykh Ibn ‘Uthaymeen said:
“As for Friday, it is not Sunnah to fast on this day, and it is makrooh to single it out for fasting.”
(Al-Sharh al-Mumti’, Vol. 6, Page. 465)
Excluded from this prohibition is one who fasts the day before or after, or if it coincides with days that he habitually fasts, such as one who fasts al-Ayyaam al-Beed (the 13th, 14th and 15th of each hijri month), or who has the habit of fasting a specific day such as the Day of ‘Arafat, and it coincides with a Friday. From this it may be understood that it is permissible for a person who has vowed to fast on the day when So and so returns, for example, or the day when So and so recovers from sickness, to observe that fast if that day happens to be a Friday. Similarly, if ‘Ashoora’ or Arafaat coincides with a Friday, he may fast, because his intention is to fast ‘Ashoora’ or ‘Arafaat, not to fast on a Friday..
(Fath al-Baari by Ibn Hajar).
The same applies to one who has fasts to make up from Ramadaan. “It is permissible for a Muslim to fast on a Friday to make up a day from Ramadaan, even if he fasts the Friday on its own.”
(Fatwa al-Lajnah al-Daa’imah, Vol. 10, Page. 347)
