Rūḥ partially coincident with Holy Spirit
The Spirit (Arabic: الروح, al-rūḥ) is mentioned twenty one times in the Quran, where it is described as issuing from the command of God. The spirit acts as an agent of divine action or communication. 
The Quran describes the rūḥ in various ways. It refers to ruh as rūḥ al-qudus, which means "the holy spirit" and ar-rūḥ al-amin, which means "the faithful" or "trustworthy spirit", terms that are commonly understood to be references to the archangel Gabriel. The Quran also refers to ruh as God's own spirit ("My/His Spirit"), which was blown into Adam, and which is considered the source of human life. Most commentators interpret the phrase "My/His (God's) Spirit" in 15:29, 32:9 and 38:72 figuratively as God's power and way of honoring Adam, with some taking a more literal view. This spirit leaves the human body at death, and continues to exist in the afterlife. Further, ruh appears to be a metaphorical being, such as an angel. In one instance, rūḥ refers to Jesus.
Early Quranic commentators generally interpreted "ruh" as meaning the soul, but this interpretation has been criticized as being flawed, extra-Quranic and influenced by anthropocentrism.In the Quran
The word "ruh" appears 21 times in the Quran, and in five of those instances, it is used in conjunction with the verb "nafakha," meaning "to blow," suggesting that it is related to blowing. Additionally, its usage is linked to concepts such as peace (97:4), assistance (58:22;  2:87), and life (15:29). In the Quran, the rūh is described as having the ability to infuse life into inanimate matter and perform other tasks beyond human comprehension. Its abilities are depicted as crossing vast distances and time spans, as it ascends to the heavens in a day that is fifty thousand years long (70:4) and animates lifeless objects. The Quran portrays rūh in different ways: as a person who obeys God and brings revelation, or as a general concept, particularly as the inspiration for Muhammad's prophetic messages. Rūh can take several forms as a person, most commonly as a metaphysical being similar to an angel (78:38), but it can also appear in human form, such as in the case of the rūh that interacts with Mary (19:17). The Quran even describes Jesus as rūh in one instance (4:171).  Additionally, rūh is referred to as Rūh al-Qudus (the Holy Spirit), al-Rūh al-Amin (the Trustworthy Spirit), or simply al-Rūh, and My/His (God's) Rūh.The Quran, however, doesn't offer a definitive explanation of the Spirit (al-ruh). It merely says in response to the question about the Spirit, "Say, “The Spirit (al-ruh) is from the Command of my Lord, and you have not been given knowledge, save a little”" (17:85), suggesting the unknowable nature of ruh.  According to The Study Quran, the term "Spirit" may refer to the source of human life, as God breathes His Spirit into Adam (32:9). This led some Muslim thinkers to believe that the Spirit is the source of human knowledge, perception, and spiritual ability. Accordingly, the Spirit is also seen as the origin of religious, moral, and spiritual responsibility for human beings. The meaning of the phrase "I...breathed into him of My Spirit" (15:29; cf 38:72, 32:9) is interpreted differently by various commentators. Most commentators believe that "My or His Spirit" refers to God's power and a way of honoring Adam, with some understanding it more literally to refer to the Spirit (al-rūḥ) of God. The latter interpretation explains why Iblīs was commanded to bow before Adam. Rūh al-Qudus (the Holy Spirit), al-Rūh al-Amin (the Trustworthy Spirit) are generally understood as references to the archangel Gabriel.The holy or trustworthy spirit
Rūḥ al-qudus (Arabic: روح القدس, "the holy spirit" or "spirit of holiness"), ar-rūḥ al-amin (Arabic: الروح الأمين, "the faithful/trustworthy spirit"), is a Quranic expression that describes a source or means of prophetic revelations, commonly identified with the angel Gabriel. Quranic commentators disagreed in their identification of Gabriel with various uses of the word rūḥ. For some, ar-rūḥ is simply the angelic quality bestowed upon humans, but not an angel himself.
The phrase rūḥ al-qudus, commonly translated as the "holy spirit" or the "spirit of holiness", occurs four times in the Quran, in  Quran 2:87 and 253, Al-Ma'idah verse 110, and An-Nahl verse 102. In three instances, it is described as the means by which God "strengthened" Jesus, and in the fourth it is identified as the one brought down God's truth to his prophet.
