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

(91) Then We raised them up that We might know which of the two parties was best able to compute the time for which they remained.

(92) And thus did We rouse them that they might question each other. A speaker among them said: How long have you tarried? They said: We have tarried for a day or a part of a day. (Others) said: Your Lord knows best how long you have tarried. Now send one of you with this silver (coin) of yours to the city, then let him see which of them has purest food, so let him bring you provision from it, and let him behave with gentleness, and by no means make your case known to any one:

(93) And on that day We will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together;

(94) But parties from among them disagreed with each other, so woe to those who disbelieve, because of presence on a great day.

(95) And when Our clear communications are recited to them, those who disbelieve say to those who believe: Which of the two parties is best in abiding and best in assembly?

(96) Bear then patiently what they say, and glorify your Lord by the praising of Him before the rising of the sun and before its setting, and during hours of the night do also glorify (Him) and during parts of the day, that you may be well pleased

(97) O people! if you are in doubt about the raising, then surely We created you from dust, then from a small seed, then from a clot, then from a lump of flesh, complete in make and incomplete, that We may make clear to you; and We cause what We please to stay in the wombs till an appointed time, then We bring you forth as babies, then that you may attain your maturity; and of you is he who is caused to die, and of you is he who is brought back to the worst part of life, so that after having knowledge he does not know anything; and you see the earth sterile land, but when We send down on it the water, it stirs and swells and brings forth of every kind a beautiful herbage.

(98) There does not reach Allah their flesh nor their blood, but to Him is acceptable the guarding (against evil) on your part; thus has He made them subservient to you, that you may magnify Allah because He has guided you aright; and give good news to those who do good (to others).

(99) And who guard their private parts,

(100) But they cut off their religion among themselves into sects, each part rejoicing in that which is with them.
