Silsilah as-Sahihah 1492 — Child may resemble any ancestor up to Adam

Sayyiduna Malik bin Huwairith (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When Allah Almighty intends to create a human being, a man has intercourse with his wife, and his semen spreads in every vein and muscle of the woman. When the seventh day arrives, Allah Almighty brings forth every vein (i.e. ancestral line) between him and Adam (peace be upon him). The Prophet (peace and blessings be upon him) then recited this verse: "In whatever form He willed, He assembled you." (Surah Infitar: 8)."
