Imam al-Sadiq (AS) said, ‘Counsel should only be sought whilst fulfilling its four terms. Firstly that the one whose counsel you seek must be a man of intellect. Secondly that he must be a free and religious man. Thirdly, he must be brotherly and friendly, and fourthly that when you disclose your secret to him whereby he knows as much about it as you do, he would keep your secret and guard it well.
