سلام علیکم

What it means

سلام علیکم (salâm aleykom) is the full Arabic greeting meaning “peace be upon you.” In Persian it is the formal, Islamic register version of the everyday سلام (salâm, “hello”). The short سلام is a contraction of this longer phrase.

You hear the full version mainly from religious Iranians (clergy, observant families, mosque settings) and in formal or diplomatic contexts. Two strangers who recognize each other as religious will often open with the full salâm aleykom rather than just salâm. It signals shared identity.

How to use it

• سلام علیکم (salâm aleykom) “peace be upon you” (greeting)
• و علیکم السلام (va aleykom-os-salâm) “and upon you peace” (the standard reply)
• سلام علیکم حاج آقا (salâm aleykom hâj âghâ) “peace upon you, sir” (to an older religious man)

Religious context

The full phrase is Arabic: as-salâmu ʾalaykum, the standard Muslim greeting across the Islamic world. It comes from the Quran and is part of the social etiquette taught in hadith literature: that a Muslim should greet another Muslim with peace, and that the reply should be equal or better.

In Iran, register matters more than ideology. A secular Tehrani in 2025 will almost always say plain سلام. A clergyman, a religious shopkeeper, a relative who prays five times a day, will more naturally say سلام علیکم. Hearing it tells you something about the speaker before they say anything else.

The reply is fixed: و علیکم السلام (va aleykom-os-salâm), “and upon you peace.” In casual speech this often shortens to va aleykom salâm, dropping the Arabic article. If someone offers the full salâm aleykom and you reply with just salâm, you have technically given less than you received, which the etiquette books frown on. In practice no one will correct you.

For learners: plain سلام is safe in every situation. Use the long form only when you have a reason: addressing a cleric, entering a mosque, greeting a religious elder who has used it with you first.

The greeting also has a diplomatic register. Iranian state media open formal addresses with سلام علیکم, as do speakers at religious or government ceremonies. Hearing the long form in a televised speech is so common that for many secular Iranians it now feels like a state-media tic rather than a personal greeting. This is one of those words whose meaning depends almost entirely on who is saying it and where.

One pronunciation note: the second word is often heard as aleykom in Iranian Persian, with a short e where the Arabic original has a long a. This is the standard Persian rendering. Spelling stays فيكم with the Arabic vowels, but speakers do not lengthen them.
