Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said that Sayyiduna Abu Bakr (may Allah be pleased with him) was sitting in the mosque when a man came and began talking in a roundabout way, and he was agitated. So he said to Sayyiduna Umar (may Allah be pleased with him): Ask him what has happened; is there some matter? Sayyiduna Umar (may Allah be pleased with him) went to him, and he told him that a guest had stayed with him and had intercourse with his daughter. Sayyiduna Umar (may Allah be pleased with him) struck him on the chest and said: May Allah disgrace you! Why did you not conceal (the matter of) your daughter? Then Sayyiduna Abu Bakr (may Allah be pleased with him) summoned them both, applied the prescribed punishment, then married them, and exiled them for one year.
Ali (Ibn al-Madini) said: This is how Muhammad bin Ishaq narrated it from Nafi' from Ibn Umar, but Ubaydullah bin Umar differed with him in its chain and its wording.
