What has the author Luqman written?

You're likely referring to Luqman the Wise, a figure mentioned in the Quran. He was not an author in the traditional sense; instead, he is revered as a wise man whose stories and teachings were passed down through generations.

The Quran specifically mentions a Surah (chapter) named Luqman (Chapter 31), which contains several verses detailing his wisdom and advice.

Here are some of the key themes found in the Surah of Luqman:

* Monotheism and the importance of worshipping only Allah: This is a central theme, emphasized by Luqman's instructions to his son.

* Gratitude and humility: Luqman teaches his son to be thankful to Allah for his blessings and to remain humble.

* Good manners and conduct: He emphasizes the importance of being respectful, honest, and kind.

* The dangers of arrogance and pride: Luqman warns his son against the pitfalls of pride and arrogance.

* The importance of seeking knowledge: He encourages the pursuit of knowledge and understanding.

While Luqman didn't write a book or text as we know it, his wisdom has been preserved in the Quran and is a significant source of ethical and spiritual guidance for Muslims.
