Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said:“(In this world) we are the last to come, but on the Day of Resurrection we will be the first. The reason for this is: those people were given the Book before us, and we were given the Book after them. So this is the day which Allah made obligatory upon them, and then Allah guided us regarding it. So, in this matter, people follow us. The day of the Jews is tomorrow (Saturday), and the day of the Christians is the day after (Sunday).”
