Sahih Muslim Book - 7, Hadith - 1980

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ وَزُهَيْرُ بْنُ حَرْبٍ قَالاَ حَدَّثَنَا جَرِيرٌ عَنِ الأَعْمَشِ عَنْ أَبِى صَالِحٍ عَنْ أَبِى 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 الَّذِى اخْتَلَفُوا فِيهِ هَدَانَا اللَّهُ لَهُ - قَالَ يَوْمُ الْجُمُعَةِ - فَالْيَوْمُ لَنَا وَغَدًا لِلْيَهُودِ وَبَعْدَ غَدٍ لِلنَّصَارَى ».

It was narrated that Abu Hurairah said: "The Messenger of Allah (s.a.w) said: 'We are the last, but the first on the Day of Resurrection and we will be the first to enter Paradise, although they were given the Book before us and we were given it after them, but they differed and Allah guided us concerning that wherein they differed of the truth. This is their day concerning which they differed; Allah has guided us to it'" - he (the narrator) said: "Friday" - " 'this day is for us, the next day is for the Jews, and the day after that is for the Christians.'"
