"Mashallah" or "Mash'Allah" is an Arabic phrase used to show appreciation for a person or happening. It shows respect, and also reminds that everything is achieved by the will of God. The closest English translation is "God willed it." It is used to show joy and praise, and is evoked upon hearing good news.

The phrase has found its way into the language of non-Arabs, including Turks and peoples of the Balkans, including some who are not of the Islamic faith.

A term used to reference cannabis/marijuana/weed.

The Arabic phrase/term MashAllah or Masha-Allah is short for the longer phrase “Mashallah-Allah Tabarak Allah” which literally translates into “that in which God has willed, He has or will bless”. However, the closest meaning and use of the phrase in the English language is that similar to the phrase “Knock on wood” to express hope for someone’s good luck to continue for a particular positive statement or as to not jinx something good.

"Amen" for Muslims. If you omit to say mashallah when someone did something well, you'll be blamed if things go wrong.
