Abu Huraira reported the Prophet as saying, “When one of you visits his brother Muslim he should eat of his food without asking questions and drink from what he provides without asking questions.”
Baihaqi transmitted the three traditions in Shu'ab al-iman, saying that if is sound, it is because a Muslim would obviously give him only food and drink which were lawful in his opinion.
‘A’isha told that when Sauda became old she said, “Messenger of God, I appoint to ‘A'isha the day you visit me” (Cf. the last tradition in this chapter). So God’s Messenger allotted two days to ‘A’isha, hers and Sauda’s.
