‘Amr b. Shu'aib, on his father’s authority, said that his grandfather told of a man who got up and said, “Messenger of God, so and so is my son; I had illicit intercourse with his mother in the pre-Islamic period.” God’s Messenger replied, “There is no unlawful claiming of paternity in Islam. What was done in pre-Islamic times has been annulled. The child is attributed to the one on whose bed it is born, and the fornicator is deprived of any right.” Abu Dawud transmitted it.
