Prophet Musa (a.s) requested to Allah: “O’ Lord! Show to me who, from amongst all Your creations, is the best person who worships You.” Allah revealed to him: “Proceed towards the village situated near the sea-shore and you shall find the person there.”
Reaching there Musa (a.s) found a leper, who was engaged in praising and glorifying Allah. He (a.s) asked Jibra`il: “Where is the person whom I had sought from Allah?” Jibra`il pointed to the sick person and said: “This is the person! I am under instructions to take away his eyes; pay careful attention to what he shall say.”
Having said this, he pointed towards the leper’s eyes and they suddenly popped out of their sockets. As soon as this happened, the leper said: “O’ Allah! Till You desired you let me benefit from my eyes and now You have desired to take them away from me. O’ The One! Who does good to me and provides me with goodness.”
Approaching him, Musa (a.s) said: “O’ Servant of Allah! I am a person whose prayers are always accepted; if you desire, I shall pray to Allah so that He returns your eyes to you.”
The man said: “No, I do not desire it. Allah has desired this state for me and I am pleased with all that pleases Him.”
Musa (a.s) said: “I heard you say: “O’ The One! Who does good to me and provides me with goodness. What did you mean by these words?”
He said: “In this village I am the only one who is cognizant of Allah and worships Him (what goodness could be greater than this that He has made me aware and cognizant of Himself.)” Musa (a.s) was overcome by astonishment and amazement, and as he turned back, he said to himself: “He is the greatest worshipper of Allah in the world.”( Namunah-e-Ma’arif, vol. 5, pg. 373; Shaytan, vol. 1, pg. 524 )
