From Holy Quran:
Surat Al-Jumu`ah (The Congregation, Friday) – سورة الجمعة
O you who have believed, when [the adhan] is called for the prayer on the day of Jumu’ah [Friday], then proceed to the remembrance of Allah and leave trade. That is better for you, if you only knew.
From Sahih Bukhari:
Volume 2, Book 13, Number 33 :
Narrated by Salman Al-Farsi
Allah’s Apostle (p.b.u.h) said, “Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven.”
Volume 3, Book 39, Number 539 :
Narrated by Sahl bin Sad
We used to be very happy on Friday as an old lady used to cut some roots of the Silq, which we used to plant on the banks of our small water streams, and cook them in a pot of her’s, adding to them, some grains of barley. (Ya’qub, the sub-narrator said, “I think the narrator mentioned that the food did not contain fat or melted fat (taken from meat).”) When we offered the Friday prayer we would go to her and she would serve us with the dish. So, we used to be happy on Fridays because of that. We used not to take our meals or the midday nap except after the Jumua prayer (i.e. Friday prayer) .

Narrated by Abu Huraira
The Prophet said, “On every Friday the angels take heir stand at every gate of the mosques to write the names of the people chronologically (i.e. according to the time of their arrival for the Friday prayer and when the Imam sits (on the pulpit) they fold up their scrolls and get ready to listen to the sermon.”

Narrated by Nafi
Ibn ‘Umar was once told that Said bin Zaid bin ‘Amr bin Nufail, one of the Badr warriors, had fallen ill on a Friday. Ibn ‘Umar rode to him late in the forenoon. The time of the Friday prayer approached and Ibn ‘Umar did not take part in the Friday prayer. Narrated Subaia bint Al-Harith: That she was married to Sad bin Khaula who was from the tribe of Bani ‘Amr bin Luai, and was one of those who fought the Badr battle. He died while she wa pregnant during Hajjat-ul-Wada.’ Soon after his death, she gave birth to a child. When she completed the term of deliver (i.e. became clean), she prepared herself for suitors. Abu As-Sanabil bin Bu’kak, a man from the tribe of Bani Abd-ud-Dal called on her and said to her, “What! I see you dressed up for the people to ask you in marriage. Do you want to marry By Allah, you are not allowed to marry unless four months and ten days have elapsed (after your husband’s death).” Subai’a in her narration said, “When he (i.e. Abu As-Sanabil) said this to me. I put on my dress in the evening and went to Allah’s Apostle and asked him about this problem. He gave the verdict that I was free to marry as I had already given birth to my child and ordered me to marry if I wished.”

Narrated by Sahl bin Sad
We used to be happy on Fridays, for there was an old lady who used to pull out the roots of Silq and put it in a cooking pot with some barley. When we had finished the prayer, we would visit her and she would present that dish before us. So we used to be happy on Fridays because of that, and we never used to take our meals or have a mid-day nap except after the Friday prayer. By Allah, that meal contained no fat.
Volume 8, Book 74, Number 265 :
Narrated by Abu Hazim
Sahl said, “We used to feel happy on Fridays.” I asked Sahl, “Why?” He said, “There was an old woman of our acquaintance who used to send somebody to Buda’a (Ibn Maslama said, “Buda’a was a garden of date-palms at Medina). She used to pull out the silq (a kind of vegetable) from its roots and put it in a cooking pot, adding some powdered barley over it (and cook it). After finishing the Jumua (Friday) prayer we used to (pass by her and) greet her, whereupon she would present us with that meal, so we used to feel happy because of that. We used to have neither a midday nap, nor meals, except after the Friday prayer.” (See Hadith No. 60, Vol.2)
Volume 9, Book 88, Number 223 :
Narrated by Shaqiq bin Salama
I was sitting with Abu Mas’ud and Abu Musa and ‘Ammar. Abu Mas’ud said (to ‘Ammar), “There is none of your companions but, if I wish, I could find fault with him except with you. Since you joined the company of the Prophet I have never seen anything done by you more criticizable by me than your haste in this issue.” ‘Ammar said, O Abu Mas’ud ! I have never seen anything done by you or by this companion of yours (i.e., Abu Musa) more criticizable by me than your keeping away from this issue since the time you both joined the company of the Prophet.” Then Abu Mas’ud who was a rich man, said (to his servant), “O boy! Bring two suits.” Then he gave one to Abu Musa and the other to ‘Ammar and said (to them), “Put on these suits before going for the Friday prayer.”
