Once Hesham ibn Hakam, companion of Imam Baqir
(a.s.) and Imam Sadiq (a.s.) went for Hajj. He stood in
front of the Holy Kaaba with his hands raised and
profusely crying and supplicating. The people gathered
around him, when he completed the supplications,
people congratulated him saying, “Inshallah, your
supplications will be accepted.” Hisham said “I did not
ask anything for myself. The people were shocked to
hear it and asked him the reason. He said, “I heard,
Imam Baqir (a.s.) and Imam Sadiq (a.s.):
“When a believer prayers for solution of the
problems of his believing brother then the angels
say to Allah to solve his problems also”. He said
“My prayers can be rejected but the prayers of the
angels will not be rejected.
