Abu Hurayrah and Hudhayfah (r) said: The Messenger of Allah (saaws) said: "Allah led those who came before us away from Friday. The Jews had Saturday, and the Christians had Sunday. Then Allah brought us and Allah guided us to Friday. So there is Friday, Saturday and Sunday, and thus they will follow us on the Day of Resurrection. We are the last of the people of this world but we will be the first on the Day of Resurrection, and we will be dealt with before all others."

[Sahih Muslim, #856]
