Sahih al-Bukhari Book 68, Hadith 55
An Ansari man accused his wife (of committing illegal sexual intercourse). The Prophet (ﷺ) made both of
them takes the oath of Lian, and separated them from each other (by divorce).
A man came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! A black child has been born for me." The Prophet asked him, "Have you got camels?" The man said, "Yes." The Prophet (ﷺ) asked him, "What color are they?" The man replied, "Red." The Prophet (ﷺ) said, "Is there a grey one among them?' The man replied, "Yes." The Prophet (ﷺ) said, "Whence comes that?" He said, "May be it is because of heredity." The Prophet (ﷺ) said, "May be your latest son has this color because of heredity."
Hilal bin Umaiyya accused his wife of illegal sexual intercourse and came to the Prophet (ﷺ) to bear witness (against her), (taking the oath of Lian). The Prophet (ﷺ) was saying, "Allah knows that either of you is a liar. Will anyone of you repent (to Allah)?" Then the lady got up and gave her witness.
