Among the seven days of the week, Friday is the day of gathering for the Muslims. Many great events took place on this day, and yet to take place.
Allah Says in the Holy Quran Chapter 62 Surah Jumua verses 9-10
O ye who believe! When the call is proclaimed to prayer on Friday (the Day of Assembly) hasten earnestly to the Remembrance of Allah and leave off business (and traffic): that is best for you if ye but knew!
And when the Prayer is finished then may ye disperse through the land and seek of the Bounty of Allah: and celebrate the Praises of Allah often (and without stint): that ye may prosper.
The Messenger of Allah (saws) said:
‘It was Friday from which Allah diverted those (nations) who were before us. For the Jews (the day set aside for prayer) was Saturday, and for the Christians it was Sunday. And Allah turned towards us and guided us to Friday (as the day of Remembrance and Prayer) for us. In fact, He (Allah) made Friday, Saturday and Sunday (as days of prayer). In this order would they (Jews and Christians) come after us on the Day of Resurrection. We are the last of (the Ummah) among the people in this world and the first among the created to be judged on the Day of Resurrection.’
[Sahih Muslim Hadith 1862] – Narrated by Abu Hurayrah and Hudhayfah
Abu Hurairah reports that the Messenger of Allah (saws) said:
“The best day on which the sun rises is Friday. [On Friday] Adam was created, and on that day he entered Paradise, and on that day he was expelled from Paradise. And the Hour will come to pass on Friday.”
[Related by Muslim, Abu Dawud, an-Nasa’i, and at-Tirmidhi]
Abu Lubanah al-Badri relates that the Prophet (saws) said:
“The most prominent (or leader) of the days is the day of Jumu’ah and the most honored in Allah’s Sight, and it is more honored in Allah’s sight than the day of breaking the fast, or the day of sacrifice. It has five significant merits: Allah created Adam on this day; on this day Allah sent Adam down to the earth; on this day Allah caused Adam to die; on this day, there is a time during which if anyone asks anything of Allah it will be granted to him unless he asks for something which is forbidden; and on this day, the Hour will be established. There are no Angels close to Allah or the sky or the earth or the wind or the mountain or the sea who are not worried concerning the day of Jumu’ah (as the Hour will be established on Friday).”
[Related by Ahmad and Ibn Majah]
Salman al-Farsi reports that the Prophet (saws) said:
“A man who performs ghusl on Friday, purifies [himself] what he can, and uses dye [for his hair] or perfumes himself in his house, goes to the mosque, and does not cause separation between two people [who are already seated], prays what Allah has prescribed for him, and then listens quietly while the imam speaks, all his sins between that Friday and the next Friday will be forgiven.”
[Related by Ahmad and al-Bukhari]
Tariq ibn Shihab reports that the Prophet (saws) said:
“Al-Jumu’ah (The Friday Mid-day prayer) is a duty upon every Muslim in the community, save four: a slave, a woman, a child, or a person who is ill.”
Abu Hurairah reports that one Friday the Prophet (saws) said: “O gathering of Muslims, Allah has made this day (of Friday) an Eid for you, so make ghusl and use the miswak (on this day).”[Related by at-Tabarani]
Abu Sa’id reports that the Prophet (saws) said:
“Every Muslim should have a ghusl on Friday and wear his best clothing, and if he has perfume, he should use it.”
