What is the best book for non-specialists that discusses the attributes of Allah Almighty, and why can't a created being comprehend Allah Almighty through knowledge, as stated in the noble verse: "And they do not encompass Him in knowledge"? Is that absolutely impossible, and can a servant comprehend the essence of Allah in Paradise?

There are many books on the attributes and names of Allah. Among the good contemporary books, easy in style and suitable for non-specialists, are: (Al-Qawa'id al-Muthla fi Sifat Allah wa Asma'ihil-Husna) by Ibn Uthaymeen, (Al-Sifat al-Ilahiyyah fil-Kitab was-Sunnah) by Muhammad Aman al-Jami, (Manhaj wa Dirasat li Ayati al-Asma' was-Sifat) by Muhammad al-Amin al-Shanqeeti, (Sifat Allah Azza wa Jall al-Waridah fil-Kitab was-Sunnah) by Alawi bin Abd al-Qadir al-Saqqaf, and (An-Nahj al-Asma fi Sharh Asma' Allah al-Husna) by Muhammad al-Hamoud.
