Sunan Ibn Majah 34074
In-book no 4241حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَعَمْرُو بْنُ عَبْدِ اللَّهِ، قَالاَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ نُسَيْرِ بْنِ ذُعْلُوقٍ، قَالَ كَانَ ابْنُ عُمَرَ يَقُولُ لاَ تَسُبُّوا أَصْحَابَ مُحَمَّدٍ ـ صلى الله عليه وسلم ـ فَلَمَقَامُ أَحَدِهِمْ سَاعَةً خَيْرٌ مِنْ عَمَلِ أَحَدِكُمْ عُمْرَهُ .
It was narrated that Nusair bin Dhu'luq said: "Ibn 'Umar used to say: 'Do not revile the Companions of Muhammed, for the stay of anyone of them for a brief period (with the Prophet) is better than all the good deeds that anyone of you does in his lifetime.'"
