Khal was born in Al-Mijannah, Saudi Arabia in 1962. He left his home village at a young age and currently lives in Jeddah. His works, written in a distinctive style that blends Qur'anic Arabic with dialectal (specifically Hijazi) Arabic, have made him known within and beyond the Arab world. Khal studied political science before becoming a novelist and his works criticize the corruption of the very wealthy in the Arab world. They are unavailable in his home country. According to himself, this is because they "address the sacrosanct trio of taboos in the Arab world: sex, politics, and religion". Due to Khal winning the International Prize for Arabic Fiction, his works are expected to soon be translated into various languages and become more known outside the Arabic-speaking world.
