It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "We are the last to come in terms of this world, and the foremost on the Day of Resurrection." One of the two said "ba'ida" and the other said "bayda"; the Prophet (peace and blessings be upon him) said: "They were given the Book before us and we were given the Book after them. Then this day, which Allah made obligatory upon them, they differed about it. Then Allah guided us to it, and people follow us in it: the Jews a day after and the Christians two days after."
