Supplication (also known as petitioning) is a form of prayer, wherein one party humbly or earnestly asks another party to provide something, either for the party who is doing the supplicating (e.g., "Please spare my life.") or on behalf of someone else.
Comprehensive Supplications
Abu Malik, Sa'd Bin Tariq, narrated from his father that :when a man had come to the Messenger of Allah (saas), he heard him say: "O Messenger of Allah, what should I say when I ask of Allah?" He said: "Say:Allahumma-ghfirli warhamni wa 'afini warzuqniاللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَعَافِنِي وَارْزُقْنِي(O Allah, forgive me, have mercy on me, keep me safe and sound and grant me provision),"and he held up his four fingers apart from the thumb and said: "These combine your religious and worldly affairs."

O Allah, grant health in my body, O Allah, grant health in my hearing, O Allah, grant health in my sight. There is no god worthy of being worshipped except You.
Narrated AbuBakrah (R.A):
AbdurRahman ibn AbuBakrah said that he told his father: O my father! I hear you supplicating every morning: “O Allah! Grant me health in my body. O Allah! Grant me good hearing. O Allah! Grant me good eyesight. There is no god but Thou.” You repeat them three times in the morning and three times in the evening.
He said: I heard the Messenger of Allah (ﷺ) using these words as a supplication and I like to follow his practice. [Sunan Abu Dawud 5090]
