Hazrat Imam Ali (a.s) supplication when he was ill

In the name of Allah the Beneficent the Merciful.

O Allah! Whenever You bestow a bounty upon me, my thanks is always less and whenever You have tried me in calamities, my patience was always less. 
Then O the one who never made my thanksgiving being low, and O the one who, when sent the calamities my patience was very less inspite of which 
He never deprived me of anything and O He who sees me doing sins but never degraded me. 
And O He who saw me openly committing sins but never punished me. Send blessings on Mohammad and his progeny, and grant me cure from this sickness without a speck of doubt You have power over all things.
