It has been narrated form Abi Ja'far [Imam Muhammad ibn 'Ali al-Baqir] (peace be upon him) that:
“Islam is built on five foundations: Salat, Zakat, Sawm, Hajj and Wilayat – and there was no call to any of these resembling that which the people were called towards in order to accept the Wilayah on the Day of Ghadir.”
Al-Kafi, Volume 2, Page 21, Hadith 8
