Hey! I have foreign coin which i can not read or understand. [Risolto]

Hey! I was looking trough my granny's sisters coins and found this one. I can't understand it and it doesn't have any English writing. Would anyone know where is this coin from or anything helpful. Thank you for your time and help.

Hello and welcome to Numista!

Saudi Arabia 50 Halalah https://en.numista.com/catalogue/pieces7843.html
Year 1400 (1980)

Actually, it has just enough "English" writing. It has 50. That along with the year (1400) circled in the picture is all you need. A search of year=1400 and lettering=50 returns 4 coins, one of which is yours. https://en.numista.com/catalogue/index.php?r=&ct=coin&tb=y&tc=y&tn=y&tp=y&tt=y&cat=y&ru=&ca=3&no=&v=&d=&i=50&a=1400&dg=&m=&f=&t=&w=&u=&g=&se=&c=&wi=&sw= The year is easily determined using the Islamic calendar in the Numisdoc https://en.numista.com/numisdoc/calendar-islamic-30.html .
