Prayer of a Sick Person

Imam Baihaqi has stated on the authority of Hadhrat Ali (ra) who
stated: "Once, I was present with the Prophet (peace be upon him). At
that time, I had fallen so much sick that I prayed to Allah Almighty
to grant me death if I amdestined to die so that I may get relief from
the sickness, otherwise, I may be restored to normal health from the
sickness if I have to live for sometime. I, also, prayed for being
granted patience if this sickness is a test for me from Allah
Almighty." Hearing that, the Prophet beat Ali with hisfoot and
observed: "Oh Ali! repeat what you were saying." Ali (ra) repeated his
prayer. Then the Prophet prayedto Allah Almighty: "O Allah! Heal him
from the sickness." Ali (ra) stated that he became healthy the same
day and the pain never appeared again.
