`Uqba bin Al-Harith said that he had married the daughter of Abi Ihab bin `Aziz. Later on a woman came to him and said, "I have suckled (nursed) `Uqba and the woman whom he married (his wife) at my breast." `Uqba said to her, "Neither I knew that you have suckled (nursed) me nor did you tell me." Then he rode over to see Allah's Messenger (ﷺ) at Medina, and asked him about it. Allah's Messenger (ﷺ) said, "How can you keep her as a wife when it has been said (that she is your foster-sister)?" Then `Uqba divorced her, and she married another man.
Sahih al-Bukhari Book 3, Hadith 30
← Previous Hadith I was an interpreter between the people and Ibn `Abbas. Once Ibn `Abbas said that a delegation of the tribe of `Abdul Qais came to the Prophet (ﷺ) who asked them, "Who are the people (i.e. you)? (Or) who are the delegates?" They replied, "We are from the tribe of Rabi`a." Then the Prophet (ﷺ) said to them, "Welcome, O people (or said, "O delegation (of `Abdul Qais).") Neither will you have disgrace nor will you regret." They said, "We have come to you from a distant place and there is the tribe of the infidels of Mudar intervening between you and us and we cannot come to you except in the sacred month. So please order us to do something good (religious deeds) and that we may also inform our people whom we have left behind (at home) and that we may enter Paradise (by acting on them.)" The Prophet ordered them to do four things, and forbade them from four things. He ordered them to believe in Allah Alone, the Honorable the Majestic and said to them, "Do you know what is meant by believing in Allah Alone?" They replied, "Allah and His Apostle know better." Thereupon the Prophet (ﷺ) said, "(That means to testify that none has the right to be worshipped but Allah and that Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to observe fasts during the month of Ramadan, (and) to pay Al-Khumus (one fifth of the booty to be given in Allah's cause)." Then he forbade them four things, namely Ad-Dubba.' Hantam, Muzaffat (and) An-Naqir or Muqaiyar (These were the names of pots in which alcoholic drinks used to be prepared). The Prophet (ﷺ) further said, "Memorize them (these instructions) and tell them to the people whom you have left behind."

Sahih al-Bukhari Book 3, Hadith 29 Next Hadith → My Ansari neighbor from Bani Umaiya bin Zaid who used to live at `Awali Al-Medina and used to visit the Prophet (ﷺ) by turns. He used to go one day and I another day. When I went I used to bring the news of that day regarding the Divine Inspiration and other things, and when he went, he used to do the same for me. Once my Ansari friend, in his turn (on returning from the Prophet), knocked violently at my door and asked if I was there." I became horrified and came out to him. He said, "Today a great thing has happened." I then went to Hafsa and saw her weeping. I asked her, "Did Allah's Messenger (ﷺ) divorce you all?" She replied, "I do not know." Then, I entered upon the Prophet (ﷺ) and said while standing, "Have you divorced your wives?" The Prophet (ﷺ) replied in the negative. On that I said, "Allahu-Akbar (Allah is Greater)." (See Hadith No. 119, Vol. 3 for details)
