What does Islam say about freedom of speech?

Yes, Islam values free speech, with responsibility. Speaking the truth, giving advice and even criticizing rulers are praised. At the same time, Islam treats your words as a trust you'll answer for, so lying, slander and backbiting are forbidden. In the West, Muslims enjoy legal free speech and use it within those ethics.
Your words are a trust
In Islam, speech is an amanah, something entrusted to you. The Prophet ﷺ summed it up simply: "Whoever believes in Allah and the Last Day should talk what is good or keep quiet" (Sahih al-Bukhari 6475). He also warned that a careless word, said without thinking, can cause great harm in the Hereafter (Sahih al-Bukhari 6477). That isn't a gag order. It's a reminder to think before you post, speak or share.
What Islam forbids in speech
- Lying: truthfulness leads to righteousness, while lying leads to wickedness (Sahih al-Bukhari 6094).
- Backbiting: mentioning someone in a way they'd dislike, even if it's true. If it's false, it's slander (Sahih Muslim 2589).
- Spreading rumors: the Quran says to verify news before acting on it (Quran 49:6). See Is it a sin to share fake news online as a Muslim?
- Abuse and insults: abusing a Muslim is called sinful (Sahih al-Bukhari 48), and the Quran even forbids insulting other people's gods (Quran 6:108).
Speaking truth to power
Islam doesn't want silent, fearful believers. The Prophet ﷺ said the best jihad is "a word of justice to an oppressive ruler" (Sunan Abi Dawud 4344, graded sahih). He also taught that "religion is sincerity," including sincere advice to leaders (Sahih Muslim 55). Honest, respectful criticism of people in power, including your own government, is a virtue, not disloyalty. In a democracy, that can mean writing to your representative, joining a peaceful campaign or voting. See Can I vote in elections as a Muslim?
Living with Western free-speech laws
The USA protects almost all speech under the First Amendment. The UK and most European countries also protect free expression but limit things like incitement to violence, harassment and stirring up hatred. Practically, this means:
- You're free: to practice, explain and defend Islam publicly.
- Others are free too: including to say things you find offensive. Respond with words, not threats.
- Islam asks more: something can be legal and still be sinful, like gossip or mocking people. See Is it backbiting to complain about someone online?
- Speech is a trust: speak good or stay silent.
- Lying, backbiting, slander and abuse are forbidden.
- A word of truth to an unjust ruler is among the best jihad.
- Use Western free speech fully, but within Islamic ethics.
