4. Ali has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah who has said the following: “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.’”

5. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Mahziyar from who has said the following: “Ibrahim ibn Muhammad ibn ‘Umar al-Hamadaniy once wrote to abu Ja‘far (a.s.), and asked, ‘I performed al-Hajj and I was against ’A’immah, and it was my first al-Hajj; so I entered Makkah with al-‘Umrah for al-Hajj. He (the Imam) wrote to him the answer, ‘Do your al-Hajj again.”’

He (the Imam) said, ‘Yes, it is sufficient.’”

He (the Imam) said, ‘No, but it is complete al-Hajj.’”
