There are many virtues of ghusl on the day of Jumuah.

It was narrated (through two chains) from ‘Abdur-Rahman bin Abi Sa’eed, from his father, that:

The Messenger of Allah (Sallallahu Alayhi Wasallam) said: “Ghusl on Fridays is necessary for everyone who has reached the age of puberty, and using siwak,and he should put on whatever he can find of perfume (‘Itr).”

In Ihyaaul Uloom, Imaam Ghazaali (rahmatullah alayh) states that whenever there developed a conflict between the people of Madinah and Makkah, they would say to each other: “You are worse than the man who does not take ghusl on Fridays.” Imaam Shaafi (rahmatullah alayh) said: “I never refrained from Jumuah ghusl whether at home or on a journey.” In a Hadith it is narrated that below the Arsh (Throne of Allah) are many cities filled with Angels.

They all supplicate to Allah Ta’ala to forgive those who take ghusl on Fridays and perform Jumuah Salaat.

Rasulullah (sallallahu alayhi wasallam) said that the Jumuah ghusl eradicates sins from right under the roots of the hairs on the body. To gain the virtues of ghusl it is necessary to make niyyat of ghusl.

If on a Friday one has to take ghusl of janaabat, then the niyyat of ghusl-e-janaabat should be made first. Thereafter niyyat of Jumuah ghusl should be made. The one ghusl suffices for both acts
