Musannaf Ibn Abi Shaybah 22448 — A man who picks up an abandoned child

Khalid bin Abi al-Salt (may Allah have mercy on him) said that Umar bin Abd al-Aziz (may Allah have mercy on him) said to him: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) ruled regarding a child born of fornication that he should settle the account with the one who raised him through the service he has rendered him, and for whatever remains he should work to pay it off.
