Sir Asalam waliakum there was a question in mind that what is the importance of calligraphy in Muslim society ? I will be looking forward for your answer

Exactly the same as any other society, religion has nothing to do with the art form..

Islamic calligraphy, colloquially known as Arabic calligraphy, is the artistic practice of handwriting, or calligraphy, and by extension, of bookmaking,[1] in the lands sharing a common Islamic cultural heritage. This art form is based on the Arabic script, which for a long time was used by all Muslims in their respective languages. They used it to represent God because they denied representing God with images.[2] Calligraphy is especially revered among Islamic arts since it was the primary means for the preservation of the Qur'an. Suspicion of figurative art as idolatrous led to calligraphy and abstract depictions becoming a major form of artistic expression in Islamic cultures, especially in religious contexts.[3] The work of calligraphers was collected and appreciated.

1) Calligraphy was and still is used to Preserve the Quranic Verses.
2) If a person looks at the calligraphic picture of an Ayat from the Quran he/she is reminded of their purpose in the world and it replenishes their Faith,
3) Calligraphy adds to the beauty of a house as paintings are against the islamic Shariah hence calligraphy enhances the beauty of your house too,
4) Those who do Calligraphy are surely committed to their work and it represents their love and devotion to their religion.

That's what I think are some of the important features of Islamic Calligraphy
