Selamun Aleykum is the Turkish spelling of the Arabic greeting As-salamu alaykum, used by Muslims for centuries to wish peace upon someone when meeting them. The standard reply is Wa Aleykum Selam. In Turkey and across the wider Muslim world the phrase is part of everyday speech at home, in shops and in mosques. Online it travelled through WhatsApp audios, videos and soundboards as a short, recognisable greeting clip, shared both sincerely for religious respect and lightly as a familiar hello among friends.
