Hadith.5280 - Muhammad ibn Qays narrated from one of the two Imams (peace be upon them) about a man who gouged out another man's eye, cut off his nose and ears, and then killed him.
Imam (as) said
"If he inflicted these injuries on him separately, then retaliation (qisas) will be taken for each injury, and then he will be killed. But if he struck him with a single blow that resulted in all those injuries, his neck will be struck (he will be executed), and retaliation will not be taken for the individual injuries."
