Sahih al-Bukhari Book 46, Hadith 22
We said to the Prophet, "You send us out and it happens that we have to stay with people who do not entertain us. What do you think about it? He said to us, "If you stay with some people and they entertain you as they should for a guest, accept their hospitality, but if they don't, take the right of
the guest from them."
Hind bint `Utba (Abu Sufyan's wife) came and said, "O Allah's Messenger (ﷺ)! Abu Sufyan is a miser. Is there any harm if I spend something from his property for our children?" He said, there is no harm for you if you feed them from it justly and reasonably (with no extravagance).
When Allah took away the soul of His Prophet at his death, the Ansar assembled In the shed of Bani Sa`ida. I said to Abu Bakr, "Let us go." So, we come to them (i.e. to Ansar) at the shed of Bani Sa`ida. (See Hadith No. 19, Vol. 5 for details)
