Hadith 1:166
Isnād Da'īf (Zubair `Aliza'i)
He also reported God's messenger as saying, “Follow the main body, for he who is separate from it will be separate in hell.” The source is lacking. The editor of Damascus edition quotes Mirak Shah as saying Ibn Majah gives this tradition from Anas. Ibn Majah (fitran, 8) has part of this in a tradition from Anas.
وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «اتَّبِعُوا السَّوَادَ الْأَعْظَمَ فَإِنَّهُ مَنْ شَذَّ شَذَّ فِي النَّارِ» . رَوَاهُ ابْنُ مَاجَهْ من حَدِيث أنس
