“I once wrote to abu ‘Abd Allah (a.s.), and asked him about a man who did not believe in this issue (the Divine Authority of ’A’immah); then Allah granted him understanding and belief in it. Does he still owe Hajjahta al-Islam or it is complete?’ He (the Imam) said, ‘He has completed the obligation from Allah but performing al-Hajj is more beloved to me.’ I asked about a man of the people of al-Qiblah (al-Ka‘bah) who had animosity toward ’A’immah, but Allah granted him understanding and recognized this issue (the Divine Authority of ’A’immah); does this complete his Hajjahta al-Islam or he is required to perform al-Hajj in future? He (the Imam) said, ‘Al-Hajj is more beloved to me.’”
