Ibn ‘Abbas said

‘A’isha gave a woman relative of hers among the Ansar in marriage and Allah's Messenger ﷺ came and said, “Have you escorted the girl to her husband?” On being told that they had, he asked whether they had sent someone along with her to sing, and when she replied that they had not, he said, “The Ansar are a people who give a place to love songs. I wish you had sent with her someone to say, ‘We have come to you, we have come to you; so may Allah preserve us and preserve you’.” Ibn Majah transmitted it.
