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.'"

حَدَّثَنَا 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 ﷺ فَلَمَقَامُ أَحَدِهِمْ سَاعَةً خَيْرٌ مِنْ عَمَلِ أَحَدِكُمْ عُمْرَهُ .
