The word(s) "part" appears 186 time(s) in 159 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) And if they had kept up the Taurat and the Injeel and that which was revealed to them from their Lord, they would certainly have eaten from above them and from beneath their feet there is a party of them keeping to the moderate course, and (as for) most of them, evil is that which they do

(42) Say: He has the power that He should send on you a chastisement from above you or from beneath your feet, or that He should throw you into confusion, (making you) of different parties; and make some of you taste the fighting of others. See how We repeat the communications that they may understand.

(43) And how should I fear what you have set up (with Him), while you do not fear that you have set up with Allah that for which He has not sent down to you any authority; which then of the two parties is surer of security, if you know?

(44) And on the day when He shall gather them all together: O assembly of jinn! you took away a great part of mankind. And their friends from among the men shall say: Our Lord! some of us profited by others and we have reached our appointed term which Thou didst appoint for us. He shall say: The fire is your abode, to abide in it, except as Allah is pleased; surely your Lord is Wise, Knowing.

(45) And they set apart a portion for Allah out of what He has created of tilth and cattle, and say: This is for Allah-- so they assert-- and this for our associates; then what is for their associates, it reaches not to Allah, and whatever is (set apart) for Allah, it reaches to their associates; evil is that which they judge.

(46) And they say: What is in the wombs of these cattle is specially for our males, and forbidden to our wives, and if it be stillborn, then they are all partners in it; He will reward them for their attributing (falsehood to Allah); surely He is Wise, Knowing.

(47) Lest you say that the Book was only revealed to two parties before us and We were truly unaware of what they read.

(48) Surely they who divided their religion into parts and became sects, you have no concern with them; their affair is only with Allah, then He will inform them of what they did.

(49) A part has He guided aright and (as for another) part, error is justly their due, surely they took the Shaitans for guardians beside Allah, and they think that they are followers of the right

(50) And if there is a party of you who believe in that with which am sent, and another party who do not believe, then wait patiently until Allah judges between us; and He is the best of the Judges.
