مبارک

Mobârak is the all-purpose congratulations sticker. Iranian shops put up banners reading نوروز مبارک in the two weeks before the new year. Family group chats fill with عید مبارک during religious holidays. When a friend buys a new phone, you say گوشی نو مبارک (gushi-ye now mobârak), "new phone, blessed," and they reply ممنون (mamnun, "thanks").
