The Messenger of Allah ﷺ said, "We are the last yet the foremost, even though they were given the Scripture before us and we were given it after them. This is the day which Allah prescribed for them, but they differed concerning it, and Allah
guided us to it," meaning Friday. "So the people follow us in this regard. The Jews observe it tomorrow, and the Christians the day after."
أخبرنا سعيد بن عبد الرحمن المخزومي قال حدثنا سفيان عن أبي الزناد عن الأعرج عن أبي هريرة وابن طاوس عن أبيه
قال رسول الله ﷺ نحن الآخرون السابقون بيد أنهم أوتوا الكتاب من قبلنا وأوتيناه من بعدهم وهذا اليوم الذي كتب الله عز وجل عليهم فاختلفوا فيه فهدانا الله عز وجل له يعني يوم الجمعة فالناس لنا فيه تبع اليهود غدا والنصارى بعد غد
