Page 583 o1.1 Retaliation is obligatory (A: if the person entitled wishes to take it (dis: o3.8)) against anyone who kills a human being purely intentionally and without right. (O: Intentionally is a first restriction and excludes killing someone through an honest mistake, while purely excludes a mistake made in a deliberate injury (def: o2.3), and without right excludes cases of justifiable homicide such as lawful retaliation.)
o1.2 The following are NOT subject to retaliation:
(1) a child or insane person, under any circumstances (O: whether Muslim or non-Muslim…)
(2)A MUSLIM FOR KILLING A NON-MUSLIM;
(3) a Jewish or Christian subject of the Islamic state for killing an apostate from Islam (O: because a subject of the state is under its protection, while killing an apostate from Islam is without consequences);
(4) a father or mother (or their fathers of mothers) for killing their offspring, or offspring’s offspring;
(5) nor is retaliation permissible to a descendant for (A: his ancestor’s) killing someone whose death would otherwise entitle the descendant to retaliate, such as when his father kills his mother.
