What is the significance of Friday (Jumu'ah) in Islam?

Friday is described as the best day of the week in Islamic tradition, marked by the obligatory congregational Jumu'ah prayer that replaces Zuhr for men attending it, along with recommended practices like Ghusl, wearing one's best clean clothes, applying pleasant scent, arriving early, listening attentively to the sermon, and reciting Surah Al-Kahf. It is also mentioned as containing an hour in which supplications are especially likely to be accepted, encouraging extra Dua and sending blessings on the Prophet ﷺ throughout the day.
