Is Cyber Warfare Permissible?

Shafi'i Fiqh

Answered by Shaykh Irshaad Sedick


Hacking is finding vulnerabilities in a system and using these found vulnerabilities to gain unauthorized access to the system.

Cyberwarfare uses cyberattacks against an enemy state, causing comparable harm to actual warfare and disrupting vital computer systems. Some intended outcomes could be espionage, sabotage, propaganda, manipulation, or economic warfare. It’s warfare where computers are the weapons.

My question is, is hacking permissible (according to Islam) during times of genuine war? Is this kind of warfare permissible when absolutely necessary?


In the Name of Allah, the Most Merciful and Compassionate.

May Allah alleviate our difficulties and guide us to that which is pleasing to Him.

Islam’s default position on causing harm (whether physical, psychological, or “cyber”) is that one should refrain from causing harm or reciprocating harm when a legitimate and justifiable need for harm arises (as when defending one’s life, family, religion, country, etc.,) then the only harm permitted is that which is necessary to restore justice (as detailed in Sacred Law), and Allah knows best.

Abu Saʽid al-Khudri (Allah be pleased with him) reported: The Messenger of Allah (Allah bless him and give him peace) said, “Do not cause harm or return harm. Whoever harms others, Allah will harm him. Whoever is harsh with others, Allah will be harsh with him.” [Bayhaqi, al-Sunan al-Kubra]

Allah says: “If the enemy is inclined towards peace, make peace with them. And put your trust in Allah. Indeed, He (alone) is the All-Hearing, All-Knowing.” [Quran, 8: 61]

I pray this is of benefit and that Allah guides us all.
