Musannaf Ibn Abi Shaybah 17199 — Entertainment and beating the duff

Amir bin Sa'd said: I went to Sayyiduna Ibn Mas'ud and Sayyiduna Qarazah bin Ka'b (may Allah be pleased with them both), and some girls were sitting with them singing. I said: "You are Companions of the Messenger of Allah (peace and blessings be upon him), and you do this?" He said: "Permission has been given for singing and the like at weddings."
