Shamsuddeen Muhammad bin Abee Bakr Ibn Qayyim aj-Jawzeeyah (d.751) -Rahimullaahsaid:
‘Indeed the Da’wah of the Messengers revolves around three principles:
The first principle: Knowing your Lord, the One being called to by His Names, Sifaat and His Actions.
The second principle: Knowing the path which will lead to Him and that is His remembrance, being thankful to Him and His worship which is made up of complete love for Him and complete humility for Him.
The third principle: Knowing what they will receive after reaching Him from the blessings of being in the land of His Generosity (Paradise) of which the best and the most magnificent thing will be Allaah being pleased with them and His honouring them and them seeing His Face the most High, and Allaah’s Salaam upon them and Him talking to them.’
