The book of the chaste lover Urwa ibn Hazam talks about Bani Uthra; about love in Bani Uthra, about a number of poets, then about Urwa ibn Hazam, his family, the time of his birth and death, and the fact that he grew up in Tabuk, then a description of the diwan, an analysis of the poet's poetry and an attempt to psychoanalyze this poetry, and then a publication of his poetry.

The book The World and the Science of the Study of Religions was written by Sheikh Hashim Muhammad Saeed, and what motivated him to hasten its completion after the long time that passed after he printed the first edition for students in the Sharia College in 1366 AD, is that Dr. Muhammad bin Khalil when he saw this edition, he liked it and asked to expand and print it again.
