What is the supplication of our Master Abraham that ends with, "And when I am ill, He cures me"?

Supplication (Du'a) is worship, and it is the most honored act in the sight of Allah. Allah has encouraged us to supplicate and promised to respond. The Holy Quran is filled with the supplications of prophets and righteous individuals, which Allah has recounted to us for various wisdoms, including that we may use them to supplicate to Him and draw closer to Him. Among these is the supplication of Abraham (peace be upon him) in Surat Ash-Shu'ara (The Poets):

"(He) Who created me, and He (it is Who) guides me; And He (it is Who) feeds me and waters me; And when I am ill, He heals me; And He (it is Who) causes me to die, and then will bring me to life; And Who, I hope, will forgive me my sins on the Day of Recompense. My Lord! Grant me authority and join me with the righteous; And grant me an honorable mention in later generations; And make me among the inheritors of the Garden of Delight; And forgive my father, for he was indeed among those astray; And disgrace me not on the Day when they are resurrected – The Day when neither wealth nor sons will avail, Except him who comes to Allah with a sound heart."
