How is marriage conducted, is there a specific number of invitees, what is the ruling on using music at the wedding or feast, and who is responsible for managing it?

It is recommended for a Muslim, upon entering to his wife, to be gentle with her, place his hand on her head, and supplicate for her with the reported prayers. He should also lead her in two rak'ahs of prayer and say, "In the name of Allah, O Allah, keep Satan away from us and keep Satan away from what You have bestowed upon us," when he approaches her. There is no limit to the number of invitees for the wedding feast (walimah), which is the responsibility of the husband, and it is sunnah for him to slaughter one or more sheep. Prohibitions such as music and intermingling (between sexes) must be avoided, while permissible singing and playing the daff (tambourine) are allowed for women, away from men.
