"The Messenger of Allah (ﷺ) used to accept the invitation of a slave."
Sunan Ibn Majah Book 12, Hadith 160
← Previous Hadith I heard Abu Umamah Al-Bahili say: I heard the Messenger of Allah (ﷺ) say: " No woman should spend anything from her house without her husband's permission." They said: "O Messenger of Allah, not even food?" He said: "That is among the best of our wealth."

Sunan Ibn Majah Book 12, Hadith 159 Next Hadith → "My master used to give me food and I would feed others from it, then he stopped me," or he said: "He beat me. So I asked the Prophet,” -or- "he asked him and I said: 'I will not stop.' He said: 'Both of you will be rewarded."'

Sunan Ibn Majah Book 12, Hadith 161
