The word(s) "plea" appears 161 time(s) in 140 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) The vanguard (of Islam)- the first of those who forsook (their homes) and of those who gave them aid, and (also) those who follow them in (all) good deeds,- well-pleased is Allah with them, as are they with Him: for them hath He prepared gardens under which rivers flow, to dwell therein for ever: that is the supreme felicity.

(52) Which then is best? - he that layeth his foundation on piety to Allah and His good pleasure? - or he that layeth his foundation on an undermined sand-cliff ready to crumble to pieces? and it doth crumble to pieces with him, into the fire of Hell. And Allah guideth not people that do wrong.

(53) Verily your Lord is Allah, who created the heavens and the earth in six days, and is firmly established on the throne (of authority), regulating and governing all things. No intercessor (can plead with Him) except after His leave (hath been obtained). This is Allah your Lord; Him therefore serve ye: will ye not receive admonition?

(54) Those who rest not their hope on their meeting with Us, but are pleased and satisfied with the life of the present, and those who heed not Our Signs,-

(55) But Allah doth call to the Home of Peace: He doth guide whom He pleaseth to a way that is straight.

(56) If Allah do touch thee with hurt, there is none can remove it but He: if He do design some benefit for thee, there is none can keep back His favour: He causeth it to reach whomsoever of His servants He pleaseth. And He is the Oft-Forgiving, Most Merciful.

(57) The word came: "O Noah! Come down (from the Ark) with peace from Us, and blessing on thee and on some of the peoples (who will spring) from those with thee: but (there will be other) peoples to whom We shall grant their pleasures (for a time), but in the end will a grievous penalty reach them from Us."

(58) When fear had passed from (the mind of) Abraham and the glad tidings had reached him, he began to plead with us for Lut's people.

(59) Thus did We give established power to Joseph in the land, to take possession therein as, when, or where he pleased. We bestow of our Mercy on whom We please, and We suffer not, to be lost, the reward of those who do good.

(60) So he began (the search) with their baggage, before (he came to) the baggage of his brother: at length he brought it out of his brother's baggage. Thus did We plan for Joseph. He could not take his brother by the law of the king except that Allah willed it (so). We raise to degrees (of wisdom) whom We please: but over all endued with knowledge is one, the All-Knowing.
