Salam,
Bismillah.
Bismillah.
To read about the importance of the Friday ghusl and to know whether it's compulsory or not, read this post AND the comments on it. You'll get the clear picture inshaAllah.
Now read on for the excellence or supremacy of the Friday ghusl. Yes, we know it's mustahabb (recommended), but we should also know why.
Narrated 'Abdullah bin Umar:
Allah's Apostle (p.b.u.h) said, "Anyone of you attending the Friday (prayers) should take a bath."
Narrated Ibn 'Umar:
While Umar bin Al-Khattab was standing and delivering the sermon on a Friday, one of the companions of the Prophet, who was one of the foremost Muhajirs (emigrants) came. 'Umar said to him, "What is the time now?" He replied, "I was busy and could not go back to my house till I heard the Adhan. I did not perform more than the ablution." Thereupon 'Umar said to him, "Did you perform only the ablution although you know that Allah's Apostle (p.b.u.h) used to order us to take a bath (on Fridays)?"
Narrated Abu Said Al-Khudri:
Allah's Apostle (p.b.u.h) said, "The taking of a bath on Friday is compulsory for every male (Muslim) who has attained the age of puberty."
Narrated Abu Said:
I testify that Allah's Apostle said, "The taking of a bath on Friday is compulsory for every male Muslim who has attained the age of puberty and (also) the cleaning of his teeth with Siwak, and the using of perfume if it is available." Amr (a sub-narrator) said, "I confirm that the taking of a bath is compulsory, but as for the Siwak and the using of perfume, Allah knows better whether it is obligatory or not, but according to the Hadith it is as above.")
Narrated Abu Huraira:
Allah's Apostle (p.b.u.h) said, "Any person who takes a bath on Friday like the bath of Janaba and then goes for the prayer (in the first hour i.e. early), it is as if he had sacrificed a camel (in Allah's cause); and whoever goes in the second hour it is as if he had sacrificed a cow; and whoever goes in the third hour, then it is as if he had sacrificed a horned ram; and if one goes in the fourth hour, then it is as if he had sacrificed a hen; and whoever goes in the fifth hour then it is as if he had offered an egg. When the Imam comes out (i.e. starts delivering the Khutba), the angels present themselves to listen to the Khutba."
Narrated Abu Huraira:
While 'Umar (bin Al-Khattab) was delivering the Khutba on a Friday, a man entered (the mosque). 'Umar asked him, "What has detained you from the prayer?" The man said, "It was only that when I heard the Adhan I performed ablution (for the prayer)." On that 'Umar said, "Did you not hear the Prophet saying: 'Anyone of you going out for the Jumua prayer should take a bath'?".
Narrated Salman-Al-Farsi:
The Prophet (p.b.u.h) said, "Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jumua prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutba, his sins in-between the present and the last Friday would be forgiven."
Why would you NOT take a bath on Friday, then?
Wassalam.
