Most of those sources which form the basis of our knowledge of the life of Prophet (Ibn Hishãm, al-Tabari, Ibn Sa'd, etc.) pass in silence over Muhammad's stop at Ghadir Khumm, or, if they mention it, say nothing of his discourse (the writers evidently feared to attract the hostility of the Sunnis, who were in power, by providing material for the polemic of the Shí'is who used these words to support their thesis of 'Ali's right to the caliphate).
Ahli sunat wanaitikadi ya kwamba Abubakar ni wa mwanzo kuamini kati ya wanaume, kisha ni mtu alie kuwa na usuhuba na Mtume kwa muda mrefu: Na ni mtu wa mwisho alie amuriwa na Mtume (s.a.w.w) kuwasalisha watu ambao ni uimamu mdogo, kwa hivyo jambo hilo lipimeni ya kuwa yeye awe na uimamu mkubwa).[1]
