Importance of Day of Friday Jummah Mubarak

For every ummah, there was a special day of week. For jews, saturday is special and for christians sunday is religious. For ummah of Prophet Muhammad pbuh, Friday (Jummah Mubarak) is the special day of the week. as mentioned in a sahih tradition:

Bukhari, Volume 4, Book 56, Number 693:

Narrated Abu Huraira:
The Prophet said, "We are the last (to come) but we will be the foremost on the Day of Resurrection, nations were given the Book (i.e. Scripture) before us, and we were given the Holy Book after them. This (i.e. Friday) is the day about which they differed. So the next day (i.e. Saturday) was prescribed for the Jews and the day after it (i.e. Sunday) for the Christians. It is incumbent on every Muslim to wash his head and body on a Day (i.e. Friday) (at least) in every seven days." 

On this day, a special salah is offered which is called Friday congregation prayer. Jummah salah is wajib for men but not for women, while they can still offer it and earn reward.  To understand the importance of jummah congregation, the following hadith must be read.

Bukhari, Volume 4, Book 54, Number 433:

Narrated 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." 

so, on Friday, angels note down the names of those who come for prayer and also listen to the khutbah. Here, another important point of concern arises that the sermon should be informative and no where any sectarian based. Because what the imam speaks is listened by humans and angels.

The importance of this special prayer can be judged from the fact that ALLAH swt specially revealed a verse on this which is given below,

Al-Quran-62:9 �Oh you who believe! On Friday, when the call sounds for the (congregational) prayers, rush towards it and halt all trade (and business) activity. That is better for you, if you only knew!�

on Friday, Muslims are ordered to go for salah instead of indulging themselves in world's things like trade and other stuff. Jummah is such a blessed day that on this day, many special and blessed things happened in history. Like, the last hajj performed by prophet Muhammad pbuh was on friday. On that day, the last verse of holy Quran was revealed which indicated the perfection of deen islam and ALLAH swt said that HE has liked Islam for us.  In sahih al bukhari, It is mentioned that;

Bukhari, Volume 9, Book 92, Number 373:

Narrated Tariq bin Shihab:
A Jew said to 'Umar, "O Chief of the Believers, if this verse: 'This day I have perfected your religion for you, completed My favors upon you, and have chosen for you, Islam as your religion.' (5.3) had been revealed upon us, we would have taken that day as an 'Id (festival) day." 'Umar said, "I know definitely on what day this Verse was revealed; it was revealed on the day of 'Arafat, on a Friday." 

this hadith indicates that Jews envied Muslims. There was not a nation before ummah of Muhammad pbuh who received such a glad tiding from ALLAH swt before. So, the Jew said that they would have celebrated it as eid.  From the above narration, it is also noted that friday is actually not less than eid. It is the weekly eid for muslim ummah. This is why which this day are attached so many blessings.

According to a sahih hadith mentioned in sahih bukhari:

Bukhari, Volume 7, Book 63, Number 216:

Narrated Abu Huraira:
Abul Qasim (the Prophet ) said, "There is an hour (or a moment) of particular significance on Friday. If it happens that a Muslim is offering a prayer and invoking Allah for some good at that very moment, Allah will grant him his request." (The sub-narrator placed the top of his finger on the palm of the other hand between the middle finger and the little one.) 

So, of all the week days, Friday is that day which contains a confirm moment of prayer acceptance. This is a great blessing. According to the other authentic ahadith, the moment is between asar and maghrib salah.
On Friday, it is recommended to recite surah al-kahaf. According to the authentic ahadith, this surah is protectant against fitnah of dajjal. Here an important point to note is that the fitnah of dajjal cannot be called a phenomenon of end times, rather dajjal has been born, he exists and his followers also exist. And his fitnah is very visible now a days like weakness of iman, love of duniyah.

So this surah is a shield against all these fitnah. Secondly, it is also narrated in sahih ahadith that the one who recites surah kahaf, a line of noor spreads from him and fills till the next Friday. Thus, the day of Jummah Mubarak is the day when our deen was perfected for us. This day contains blessings and bundles of reward for us. So follow sunnah and earn the reward.
