Hawzah News Agency – Imam Sajjad peace be upon him says:

حَقُّ المُستَشيرِ إنْ عَلِمتَ أنَّ لَهُ رَأياً أشَرتَ علَيهِ، وإن لَم تَعلَمْ أرشَدتَهُ إلى‏ مَن يَعلَمُ.

‘The right of the one who seeks your counsel is that you point him in the right direction if you know that he is inclined towards a certain opinion, and if you do not know [which way to point out], then you must guide him to someone who does.’
