cannot be denied due to their fame; just as their agreement in the Inward (Al-Batin) cannot be denied by the People of Unity (Ahl al-Tawhid) who have attained its realization.

He—the Almighty—said in Surah Al-Shura: {He has ordained for you of religion what He enjoined upon Noah and that which We have revealed to you, [O Muhammad], and what We enjoined upon Abraham and Moses and Jesus—to establish the religion and not be divided therein. Difficult for the polytheists is that to which you invite them. Allah chooses for Himself whom He wills and guides to Himself whoever turns back [to Him]. And they did not become divided until after knowledge had come to them—out of jealous animosity between themselves. And if not for a word that preceded from your Lord [postponing the penalty] until a specified term, it would have been settled between them. And indeed, those who were granted inheritance of the Scripture after them are in concerning it a disquieting doubt. So to that [religion of Allah] invite, and remain on a right course as you are commanded and do not follow their inclinations...} (Al-Shura: 13-15).
