Supplication in sickness

This is the supplication # 36 from Sahifa-e-Alaviya (from Imam Ali as)

بِسْمِ اﷲِ الرَّحْمٰنِ الرَّحِیْمِ
In the name of Allah the Beneficent the Merciful.
اِلٰہِیْ کُلَّمَا اَنْعَمْتَ عَلَیَّ نِعْمَۃً قَلَّ لَکَ عَنْدَہَا شُکْرِیْ،
O Allah! Whenever You bestow a bounty upon me, my thanks is always less
وَ کُلَّمَا ابْتَلَیْتَنِیْ بِبَلِیَّۃٍ قَلَّ لَکَ عِنَدَہَا صَبْرِیْ
and whenever You have tried me in calamities, my patience was always less.
فَیَا مَنْ قَلَّ شُکْرِیْ عِنْدَ نِعْمَتِہٖ فَلَمْ یَحْرِمْنِیْ،
Then O the one who never made my thanksgiving being low,
وَ یَا مَنْ قَلَّ صَبْرِیْ عِنْدَ بَلَآئِہٖ فَلَمْ یَخْذُلْنِیْ،
and O the one who found my patience limited in facing calamities, but never deprived me
وَ یَا مَنْ تَرَانِیْ عَلَی الْخَطَایَا فَلَمْ یَفْضَحْنِیْ،
and O He who sees me doing sins but never degraded me.
وَ یَا مَنْ رَآنِیْ عَلَی الْمَعَاصِیْ فَلَمْ یُعَاقِبْنِیْ عَلَیْہَا،
And O He who saw me openly committing sins but never punished me.
صَلِّ عَلٰی مُحَمَّدٍ وَ اٰلِ مُحَمَّدٍ
Send blessings on Mohammad and his progeny,
وَ اغْفِرْلِیْ ذُنُوْبِیْ وَاشْفِنِیْ مِنْ مَرَضِیْ،
and grant me cure from this sickness without a speck of doubt
اِنَّکَ عَلیٰ کُلِّ شَیْءٍ قَدِیْرٌ.
You have power over all things.
