Sunan Ibn Majah, Volume 5, Book 36, Hadith 4038 (DarusSalam) ⓘ
It was narrated from Abu Hurairah that the Messenger of Allah said: “You will be picked over just as (good) dates are selected (separated) from its bad ones. So the best of you will be taken and the worst of you will be left, so die if you can.”
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا طَلْحَةُ بْنُ يَحْيَى، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي حُمَيْدٍ، - يَعْنِي مَوْلَى مُسَافِعٍ - عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لَتُنْتَقَوُنَّ كَمَا يُنْتَقَى التَّمْرُ مِنْ أَغْفَالِهِ فَلْيَذْهَبَنَّ خِيَارُكُمْ وَلَيَبْقَيَنَّ شِرَارُكُمْ فَمُوتُوا إِنِ اسْتَطَعْتُمْ " .
