Is practicing Arabic calligraphy as a hobby forbidden, and is there a specific type of script that is considered forbidden?

Improving and beautifying handwriting is a commendable skill, praised by many scholars and kings. A believer should intend, when learning good handwriting, a good intention, such as benefiting people with what he writes for them, so that his work becomes an act of obedience to Allah. For all skills, including reading and writing, are commendable according to the intention behind learning them; if they are used for benefit, they are a virtue, and if they are used for harm, they are evil.

Similarly, the art of Arabic calligraphy: whoever learns it with a good intention, such as benefiting people, performs a righteous deed; whoever learns it out of arrogance commits an evil act; and whoever learns it merely for the sake of improving handwriting or for profit, it is permissible. Moreover, learning the art of calligraphy necessitates learning the rules of spelling and grammar, which are noble sciences.

Practicing this art as a hobby is permissible, and it can be transformed into an act of obedience to Allah and a way to earn good deeds by writing Qur'anic verses, prophetic traditions, or wisdom, and displaying them in public places for people to benefit from.
