Had not the Grace of Allah and His Mercy been upon you, a party of them would certainly have made a decision to mislead you, but in fact they mislead none except their ownselves, and no harm can they do to you in the least. Allah has sent down to you the book, and wisdom, and taught you that which you knew not. And Ever Great is the Grace of Allah to you (O Mohammad).

There is no good in most of their secret talks except him who orders Sadaqah or Maruf or conciliation between mankind; and he who does this, seeking the good pleasure of Allah, we shall give him a great reward.

Surat Al Nisa, Ayah 113 & 114
