Is retribution (qisas) applicable to one who causes another to lose his sexual desire and ability to procreate by striking him in the testicles, whether the perpetrator is one of his parents, a stranger, or a stranger acting in concert with one of the parents?

The crime must be considered: if it was intentional, then the original ruling for it is retribution (Qisas). A condition for Qisas is not to exceed the injury. Scholars have differed regarding Qisas for crushing the testicles due to their disagreement on the possibility of fulfilling this condition, and this matter is referred to specialists. If Qisas is possible and the perpetrator is the father, scholars have differed on whether Qisas should be applied to him, and the majority do not deem it permissible. If a group participated in the crime, the majority hold that Qisas applies to all of them. If one of them is the father, then again, they have differed. The final decision in all these matters rests with the judge. If the judge rules out Qisas, then blood money (Diyya) becomes obligatory upon the perpetrator. However, if the injury was accidental, there is no Qisas; instead, Diyya is obligatory upon the perpetrator's 'Aqila (male relatives responsible for paying blood money), and the Diyya is for the injured party.
