We who are the last would be the first on the Day of Resurrection but they (other Ummahs) were given the Book before us and we were given after them, and this was the day that was prescribed for them but they disagreed on it. And Allah guided us to it. and they came after us with regard to it, the Jews observing the next day and the Christians the day following that. (Using translation from Muslim 855d)
قَالَ رَسُولُ اللهِ ﷺ نَحْنُ الْآخِرُونَ السَّابِقُونَ يَوْمَ الْقِيَامَةِ بَيْدَ أَنَّهُمْ أُوتُوا الْكِتَابَ مِنْ قَبْلِنَا وَأُوتِينَاهُ مِنْ بَعْدِهِمْ وَهَذَا يَوْمُهُمُ الَّذِي فُرِضَ عَلَيْهِمْ فَاخْتَلَفُوا فِيهِ فَهَدَانَا اللهُ لَهُ فَالنَّاسُ لَنَا فِيهِ تَبَعٌ الْيَوْمَ لَنَا ولِلْيَهُودِ غَدًا وَلِلنَّصَارَى بَعْدَ غَدٍ
