This is the book ((Explanation of the Wastiya Creed) by Sheikh Muhammad al-Haras, coming out in its third edition, which does not differ from the second edition in anything, except that some virtuous brothers suggested that the most important questions of belief that Sheikh al-Islam Ibn Taymiyyah did not address should be included with it.

Ibn Taymiyyah's book Al-Aqeedah Al-Wastiyyah, “Shaykh Al-Islam”, may Allah have mercy on him, is one of the most comprehensive and important books on the doctrine of the Ahl Al-Sunnah wal-Jama'ah, with brevity in words and accuracy in phraseology, so many scholars and students of science were keen to explain and benefit from it, including Dr. and Sheikh Saleh Al-Fawzan.
