Invitation cards for marriage and the open invitation

The questioner:
Honorable Shaykh, may Allah grant you success, are the invitation cards used for marriage today considered an open invitation, or are they a private invitation?

The Shaykh:
If he gives it to you, it is a private invitation. If he gives it to you, whether your name is on it or not, if he gives it to you, that means it is a private invitation. As for placing the cards in a place where everyone takes one, that is an open invitation.

The questioner:
Yes. Honorable Shaykh, may Allah grant you success, if the invitation is via a card, but the groom gives his brother dozens of cards and says, "Write down the names of your friends you know," is that an open invitation?

The Shaykh:
No, no, this is a private invitation, because he authorized his brother to write the names he wants. This is an invitation for which he gave permission. This is a private invitation. Yes.
