Does the woman's guardian sin if he rejects a man of good religion and character due to a lack of social standing?

The questioner:
If a man of good religion and character proposes marriage and is rejected due to a lack of social standing, does the guardian sin in doing so?

The Shaykh:
The woman's guardian, meaning.

The questioner:
Yes.

The Shaykh:
By Allah, this means following what is in the best interest. So if marrying her to a certain person would not be accepted by her relatives and would lead to fitnah (trial, discord or temptation) and harm, may Allah provide her with someone better than him, something in which there is no fitnah (trial, discord or temptation) or... yes.
