Sahih Muslim 2037
The Book of Drinks
What the guest should do if he is accompanied by someone who was not invited by the host; it is recommended for the host to give permission to the one who has accompanied the guest
Anas reported that: Allah's Messenger (ﷺ) had a Persian neighbour who made excellent soup. He prepared some for Allah's Messenger (ﷺ) and then came to him to invite him to eat. He (Allah's Messenger (ﷺ) ) said, "and her too," referring to `Aisha. The man said "No," so Allah's Messenger (ﷺ) then said "No." He returned later to invite him again, so Allah's Messenger (ﷺ) said "and her too." The man said "No," so Allah's Messenger (ﷺ) then said "No." He returned another time to invite him and Allah's Messenger (ﷺ) said, "and her too." The man said yes on this third occasion, and they then stood eagerly to go out together to the man's home.
