Hawzah News Agency – The commander of the faithful, Imam Ali peace be upon him says:

والْزَموا السَّوادَ الأعْظَمَ، فإنَّ يَدَ اللَّهِ مَع الجَماعةِ، و إيّاكُم والفُرْقَةَ، فإنَّ الشّاذَّ مِن النّاسِ للشَّيطانِ، كما أنّ الشّاذَّ مِن الغَنَمِ للذِّئبِ.

'Stay with the greater majority, for verily Allah's hand is with the [larger] group. Beware of separation for verily the deviant amongst you is the victim of Satan just as the deviant amongst the cattle is the victim of a wolf.'
