  Ali regularly represented Muhammad in missions which are commonly linked to Quranic injunctions. For instance, the verse of walaya (5:55) is a reference to when Ali gave his ring to a beggar, while praying in the mosque, according to Shia and some Sunni accounts. If so, then this verse gives Ali the same spiritual authority (walaya) as Muhammad. In Shia sources, the verse of tabligh (5:67) spurred Muhammad to designate Ali as his successor at the Ghadir Khumm, while the verse of ikmal al-din (5:3) subsequently announced the perfection of Islam. The verse of purification (33:33) concerns the status of purity of the Ahl al-Bayt (lit. ' people of the house '), which is limited to Ali, Fatima, and their two sons in Shia and some Sunni sources. Another reference to the Ahl al-Bayt might be the verse of mawadda (42:23). For Shias, this verse is a Quranic mandate to love and follow the Ahl al-Bayt.
