Controlling the Tongue: Islamic Etiquette of Speech and Silence

Every word we utter is recorded. Allah says in the Quran: “Not a word does he utter, but there is a watcher by him, ready to record it.” (Quran 50:18) The Prophet ﷺ distilled the entire fiqh of speech into a single line: “Whoever believes in Allah and the Last Day, let him say what is good or remain silent.” (Bukhari, Muslim) If taken seriously, this one principle transforms daily life more than almost any other practice.

Why the Tongue Matters More Than We Realise

In a well-known hadith, Mu‘adh ibn Jabal (RA) asked the Prophet ﷺ about the deed that takes people to Paradise and protects them from Hellfire. The Prophet ﷺ answered at length — then ended by reaching for his own tongue and saying: “Restrain this.” Mu‘adh asked: “Will we be held accountable for what we say?” The Prophet ﷺ replied: “May your mother be bereaved of you, O Mu‘adh! Is there anything that topples people on their faces — or he said: on their noses — into the Fire, except the harvests of their tongues?” (Tirmidhi, Ibn Majah)

He also taught: “A man might utter a word pleasing to Allah, without thinking much of it, and because of it Allah raises him many degrees. And a man might utter a word displeasing to Allah, without thinking much of it, and because of it he falls into Hellfire.” (Bukhari) A single unguarded sentence can erase the reward of years of worship.

Speech that Islam Forbids

• Backbiting (ghibah): Mentioning your fellow Muslim in a way they would dislike, even if it is true. The Quran compares it to eating the flesh of one’s dead brother. (Quran 49:12)
• Slander (buhtan): Saying something false about a person. Worse than backbiting and among the most serious of sins.
• Tale-carrying (nameemah): Spreading words between people to cause harm or division. The Prophet ﷺ mentioned it as a cause of punishment in the grave. (Bukhari, Muslim)
• Lying (kadhib): The Prophet ﷺ said lying leads to wickedness and wickedness leads to the Fire. (Bukhari)
• Mockery and ridicule: Allah forbids mocking others in the Quran (49:11). Even a condescending tone or subtle put-down falls under this.

Speech that Islam Encourages

The Quran commands good speech not merely as politeness but as a religious duty. The Prophet ﷺ reinforced this: “A kind word is charity.” (Bukhari, Muslim) And he said: “The best of you are those who are best in character.” (Tirmidhi) Speech is the primary arena in which character is displayed.

Practical Steps to Guard Your Speech

1. Pause before speaking. Ask: is this true? Is it necessary? Is it kind? If none of these, the silence is better.
2. Fill idle moments with dhikr. SubhanAllah, Alhamdulillah, and Allahu Akbar cost nothing and pile up reward throughout the day.
3. Change the subject when a conversation turns to backbiting. The person who stays silent while others backbite still shares in the sin if they show approval.
4. Seek forgiveness promptly. If you slip — and everyone does — make istighfar immediately and, where the sin involved a person’s honour, seek their pardon too.
5. Sit with people who speak well. The Prophet ﷺ described the righteous companion as one who reminds you of Allah when you see them.

One of the most powerful uses of the tongue is seeking Allah’s forgiveness. Our guide on the power of istighfar covers the forms, rewards, and best times for this short yet transformative act of worship — and why the Prophet ﷺ would say it over a hundred times a day.
