Is it permissible for one whose honor has been violated verbally in his absence, and who has been subjected to lies and obscene slander, to defend himself even unto death, by analogy with the Hadith: "Whoever dies in defense of his honor is a martyr"?

The person who sows discord, corruption, lies, and obscene slander, who does not establish prayer, does not uphold a covenant, and spoke obscenely about your honor, has committed many prohibitions and grave sins. Slandering a Muslim is a major sin and one of the seven destructive sins, as the Prophet, peace and blessings be upon him, said: "Avoid the seven destructive sins: associating partners with Allah, magic, killing a soul which Allah has forbidden except by right, consuming usury, consuming the property of an orphan, fleeing on the day of the battle, and slandering chaste, unsuspecting, believing women." Whoever slanders a free, adult, sane Muslim who is chaste from the indecency with which they were accused has deserved the Hadd punishment for slander. The slandered person has the right to demand that the ruler implement the punishment, and the ruler must apply the Hadd unless the slandered person pardons them. As for defending oneself to death and the notion that whoever dies defending their honor is a martyr, we have not found this in the texts we have consulted.
