Core foundations upon which the correct call to Islām is made, in alignment with the authentic Sunnah and the way of the salaf.
His eminence, Shaykh 'Abdullaah Ibn Abdul Azeez Ibn Baaz says: Allaah says: "And We made from amongst them leaders by Our Command when they had patience and firmly believed in Our Signs." [Sooratus Sajdah: 24]
The Companions of the Messenger of Allaah and whoever proceeded upon their path, trusted in this. They became leaders, guides, and callers to the truth, and they became examples to follow because of the reason that they had patience and firm belief. For verily leadership in the Religion can only be achieved through patience and firm belief. So the Companions of the Messenger of Allaah (Sallallaahu 'Alayhi Wa Sallam) and those who follow them in goodness up until our day, these are the leaders, and the guides, and the examples to be followed in the path to the truth. And from that it becomes clear upon every student of knowledge, that calling to Allaah is from the most important duties in every time and place. [Ad-Da'awah ilallaah wa Akhlaaqud Du'aat (p. 12-13)]
