Mishkat al-Masabih 1 Faith كتاب الإيمان 176

عَنْ مُعَاذِ بْنِ جَبَلٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ الشَّيْطَانَ ذِئْبُ الْإِنْسَانِ كَذِئْبِ الْغَنَمِ يَأْخُذُ الشَّاذَّةَ وَالْقَاصِيَةَ وَالنَّاحِيَةَ وَإِيَاكُمْ وَالشِّعَابَ وَعَلَيْكُمْ بِالْجَمَاعَةِ وَالْعَامَّةِ» . رَوَاهُ أَحْمد

Mu’adh b. Jabal reported God’s messenger as saying, “The devil is a wolf to man, like the wolf which harries sheep, catching the one which is solitary, the one which stays far from the flock, and the one which wanders. So avoid the branching paths and keep to the general community.” Ahmad transmitted it.
