Introduction:
All praise is due to Allah, and may blessings and peace be upon our Prophet Muhammad, his family, and his Companions.
To proceed:
This is a commentary on the Four Principles authored by the reviver, Shaykh al-Islam Muhammad b. ʿAbd al-Wahhab (may Allah have mercy on him). Having found no extant explanation of the treatise, I resolved to elucidate it according to the measure of my ability and strength.
I beseech Allah to pardon the deficiencies that I may have fallen into.
