The day of Jumu‘ah (Friday) is held sacred by Muslims. It came in a Hadith Al-Sharif as follows: “The best day on which the sun has risen is Friday. Adam (Alayhis Salam) was created on Friday, on it he entered Jannah (Paradise), and on it he was taken out from therein. The Hour will not be established but on Friday.”
Since Muslims treat Friday as an Eid (festival), they should care more for their cleanliness on it than else times. For this reason, taking Ghusl bath for Jumuah Salah, applying nice perfumes and putting on clean clothes are Sunnah and from the good manners of Islam.
On this blessed day, Muslims gather in the masajid (mosques), listen to the Khutbah (sermon), pray their Salah and make Dua (supplicate) collectively offering their needs to the Creator. By this way, they can establish a social bond and a form of Islamic brotherhood. After performing Salah, they continue doing other Ibadat (worship), visiting their friends or relatives, trading or performing other activities.
Until the caliphate of Hadhrat Uthman Radhiyallahu Anhu, Adhan was only announced when the khatib (one delivering the sermon) was ascending minbar. Starting from the governance of Hadhrat Uthman Radhiyallahu Anhu, due to the increased number of the Muslims, a second Adhan out of the masajid was then called to notify people for the beginning of the time, which was called “exterior Adhan”.
To sum up, Muslims should appreciate every auspicious moments of Fridays, engage in Ibadat (prayers) and other permissible daily acts rather than wasting their time.
The Prophet of Allâh (Sallalahu Alayhi Wa Sallam) said: “When it is Friday, all the creatures will be in fear of that (Judgement) Day except the Jinn and the humans. And indeed, the (reward of the) good deeds and the (punishment of the) evil deeds are multiplied in it.” (Abu Nuaym, Hilyah Al-Awliya)
