If you want to talk about the font of Arabic calligraphy, it doesn't really matter much. In the traditional font of Arabic calligraphy, this font is basically not included ... the closest is probably Nash style. Just as you are not sure whether the regular script in the computer is the European style or the Yan style of traditional calligraphy, the reason is the same ~ ~
The font in the picture is basically the textbook font compiled by Beijing Arabic. If you look at the textbooks outside, you will find the font equivalent to Chinese Song-style-Simplified Arabic.
