Sahih Muslim , Book 7, Hadith 30 (In-Book) ⓘ

Abu Huraira reported Allah's Messenger as saying: We are the last (but) we would be the first on the Day of Resurrection, and we would be the first to enter Paradise, but that they were given the Book before us and we were given after them. They disagreed and Allah guided us aright on whatever they disagreed regarding the truth. And it was this day of theirs about which they disagreed, but Allah guided us to it, and that is Friday for us; the next day is for the Jews and the day following for the Christians.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَزُهَيْرُ بْنُ حَرْبٍ، قَالاَ حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ نَحْنُ الآخِرُونَ الأَوَّلُونَ يَوْمَ الْقِيَامَةِ وَنَحْنُ أَوَّلُ مَنْ يَدْخُلُ الْجَنَّةَ بَيْدَ أَنَّهُمْ أُوتُوا الْكِتَابَ مِنْ قَبْلِنَا وَأُوتِينَاهُ مِنْ بَعْدِهِمْ فَاخْتَلَفُوا فَهَدَانَا اللَّهُ لِمَا اخْتَلَفُوا فِيهِ مِنَ الْحَقِّ فَهَذَا يَوْمُهُمُ الَّذِي اخْتَلَفُوا فِيهِ هَدَانَا اللَّهُ لَهُ - قَالَ يَوْمُ الْجُمُعَةِ - فَالْيَوْمُ لَنَا وَغَدًا لِلْيَهُودِ وَبَعْدَ غَدٍ لِلنَّصَارَى ‏" ‏ ‏.‏
