Sahih Muslim 8161
In-book no 884حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا أَبُو الأَشْهَبِ، عَنْ أَبِي نَضْرَةَ الْعَبْدِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى فِي أَصْحَابِهِ تَأَخُّرًا فَقَالَ لَهُمْ " تَقَدَّمُوا فَائْتَمُّوا بِي وَلْيَأْتَمَّ بِكُمْ مَنْ بَعْدَكُمْ لاَ يَزَالُ قَوْمٌ يَتَأَخَّرُونَ حَتَّى يُؤَخِّرَهُمُ اللَّهُ " .
Abu Sa'id al-Khudri reported: The Messenger of Allah (ﷺ) saw (a tendency ) among his Companions to go to the back, so he said to them: Come forward and follow my lead, and let those who come after you follow your lead. People will continue to keep back till Allah will put them at the back.
