Sahih Muslim 856aBook 7, Hadith 32
وَحَدَّثَنَا أَبُو كُرَيْبٍ، وَوَاصِلُ بْنُ عَبْدِ الأَعْلَى، قَالاَ حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنْ أَبِي مَالِكٍ، الأَشْجَعِيِّ عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، وَعَنْ رِبْعِيِّ بْنِ حِرَاشٍ، عَنْ حُذَيْفَةَ، قَالاَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَضَلَّ اللَّهُ عَنِ الْجُمُعَةِ مَنْ كَانَ قَبْلَنَا فَكَانَ لِلْيَهُودِ يَوْمُ السَّبْتِ وَكَانَ لِلنَّصَارَى يَوْمُ الأَحَدِ فَجَاءَ اللَّهُ بِنَا فَهَدَانَا اللَّهُ لِيَوْمِ الْجُمُعَةِ فَجَعَلَ الْجُمُعَةَ وَالسَّبْتَ وَالأَحَدَ وَكَذَلِكَ هُمْ تَبَعٌ لَنَا يَوْمَ الْقِيَامَةِ نَحْنُ الآخِرُونَ مِنْ أَهْلِ الدُّنْيَا وَالأَوَّلُونَ يَوْمَ الْقِيَامَةِ الْمَقْضِيُّ لَهُمْ قَبْلَ الْخَلاَئِقِ " . وَفِي رِوَايَةِ وَاصِلٍ الْمَقْضِيُّ بَيْنَهُمْ .
It was Friday from which Allah diverted those who were before us. For the Jews (the day set aside for prayer) was Sabt (Saturday), and for the Christians it was Sunday. And Allah turned towards us and guided us to Friday (as the day of prayer) for us. In fact, He (Allah) made Friday, Saturday and Sunday (as days of prayer). In this order would they (Jews and Christians) come after us on the Day of Resurrection. We are the last of (the Ummahs) among the people in this world and the first among the created to be judged on the Day of Resurrection. In one narration it is: ', to be judged among them".
