Sahih al-Bukhari Book 86, Hadith 70
The Prophet (ﷺ) used to say, "Nobody should be flogged more than ten stripes except if he is guilty of a
crime, the legal punishment of which is assigned by Allah."
A bedouin came to Allah's Messenger (ﷺ) and said, "My wife has delivered a black child." The Prophet (ﷺ) said to him, "Have you camels?" He replied, "Yes." The Prophet (ﷺ) said, "What color are they?" He replied, "They are red." The Prophet (ﷺ) further asked, "Are any of them gray in color?" He replied, "Yes." The Prophet asked him, "Whence did that grayness come?" He said, "I thing it descended from the camel's ancestors." Then the Prophet (ﷺ) said (to him), "Therefore, this child of yours has most probably inherited the color from his ancestors."
On the authority of others, that the Prophet (ﷺ) said, "No Punishment exceeds the flogging of the ten stripes, except if one is guilty of a crime necessitating a legal punishment prescribed by Allah."
