Is it permissible for a believer to supplicate to God to save his honor from being violated by enemies, and if that were to happen, how could he himself live?

The question is unclear, but generally, a Muslim is permitted to supplicate to Allah for deliverance from all harm. Allah has encouraged supplication and promised to answer it, and it is recommended to supplicate frequently in every matter. If a Muslim is afflicted with something undesirable, such as an unjust assault on their honor or wealth, they should exercise patience and seek reward, knowing that every calamity expiates sins. Furthermore, the supplication of the oppressed is answered by Allah, as the Prophet, peace and blessings be upon him, said: "Three whose supplication is not rejected: a just ruler, a fasting person until he breaks his fast, and the supplication of an oppressed person. Allah raises it above the clouds, and the gates of heaven are opened for it, and the Lord, the Mighty and Exalted, says: 'By My glory, I will surely grant you victory, even if after a while.'"
