باب هِدَايَةِ هَذِهِ الأُمَّةِ لِيَوْمِ الْجُمُعَةِ ‏
Sahih Muslim 855 a

Abu Huraira reported Allah's Messenger (ﷺ) as saying:

We who are the last shall be the first on the Day of Resurrection, except that every Ummah was given the Book before us and we were given it after them. It was this day which Allah prescribed for us and guided us to it and the people came after us with regard to it, the Jews observing the next day and the Christians the day following that.
وَحَدَّثَنَا عَمْرٌو النَّاقِدُ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ نَحْنُ الآخِرُونَ وَنَحْنُ السَّابِقُونَ يَوْمَ الْقِيَامَةِ بَيْدَ أَنَّ كُلَّ أُمَّةٍ أُوتِيَتِ الْكِتَابَ مِنْ قَبْلِنَا وَأُوتِينَاهُ مِنْ بَعْدِهِمْ ثُمَّ هَذَا الْيَوْمُ الَّذِي كَتَبَهُ اللَّهُ عَلَيْنَا هَدَانَا اللَّهُ لَهُ فَالنَّاسُ لَنَا فِيهِ تَبَعٌ الْيَهُودُ غَدًا وَالنَّصَارَى بَعْدَ غَدٍ ‏"‏ ‏.‏
