Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) said: "Among the judgments of the Prophet (peace and blessings be upon him) is that for the major aggravated diyah he fixed 30 bint labun, 30 hiqqahs and 40 that have young in their bellies, and for the minor diyah 30 bint labun, 30 hiqqahs, 20 bint makhad and 20 male banu makhad."
Ishaq bin Yahya did not meet Ubadah bin al-Samit, so it is mursal.
