Narrated Abu Huraira:

I heard Allah's Apostle (p.b.u.h) saying, "We (Muslims) are the last (to come) but (will be) the foremost on the Day of Resurrection though the former nations were given the Holy Scriptures before us. And this was their day (Friday) the celebration of which was made compulsory for them but they differed about it. So Allah gave us the guidance for it (Friday) and all the other people are behind us in this respect: the Jews' (holy day is) tomorrow (i.e. Saturday) and the Christians' (is) the day after tomorrow (i.e. Sunday)."Volume 2, Book 13, Number 2Narrated 'Abdullah bin Umar:Allah's Apostle (p.b.u.h) said, "Anyone of you attending the Friday (prayers) should take a bath."

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)?"
