'Abdullah bin Mas'ud narrated that the Messenger of Allah said:
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ ، حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا سُفْيَانُ ، عَنْ زُبَيْدِ بْنِ الْحَارِثِ ، عَنْ أَبِي وَائِلٍ ، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " سِبَابُ الْمُسْلِمِ فُسُوقٌ وَقِتَالُهُ كُفْرٌ " . قَالَ زُبَيْدٌ قُلْتُ لأَبِي وَائِلٍ أَأَنْتَ سَمِعْتَهُ مِنْ عَبْدِ اللَّهِ قَالَ نَعَمْ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"Verbally abusing the Muslim is disobedience and fighting him is disbelief." Zubaid said:"I said to Abu Wa'il: 'Did you hear it from 'Abdullah?' He said: 'Yes.'"
