7az sa3eed. I know what you are thinking:"Why are there numbers mixed in with letters?!". Well, the answer is simple. There are some sounds in the Arabic language that are not represented by letters. For example "7ah". This sound has no equivalent in the English alphabet and therefore we use the number 7 to represent the sound. And by the way the number 7 actually looks quite similar to how you would write the letter using Arabic script.

The number 3 represents the Arabic letter ع or 'ayn. You can see a list of the alphabet and their sounds here:
