My question is that I heard a lecture ; and correct me if im wrong but basically it said that we shouldnt necessairily refer to the Quran as the “Holy Quran” because Allah and His messenger (sws) have never refferred it to it like that ..so my question is what is the ruling on calling it the “holy Quran” or is it better to call it the noble Quran .

Praise
be to Allah.

There
is nothing wrong with calling the Qur’an holy (muqaddas), because
what is meant by (the Arabic word translated here as holy) is pure. 

Al-Azhari (may Allah have mercy on him) said: al-Quddoos (the Holy) – which
is one of the names of Allah – means the Pure, the One Who is above all
faults and shortcomings. 

See:
Lisaan al-‘Arab, 6/168-169 

Ibn
Jareer (may Allah have mercy on him) said: 

The
Arabic word taqdees, which means sanctifying (making holy), refers to
purification and veneration. Hence the phrase “subbooh qudoos
(glorified, holy).” What is meant by subbooh is declaring Allah to be above
all faults. What is meant by quddoos is declaring His purity and venerating
Him. Hence the land is called ard muqaddasah (holy land), i.e., it is
pure. What is meant by the angels saying Nahnu nusabbihu bi hamdika
(We glorify and praise You) is: We declare you to be above anything that the
polytheists attribute to You, and we pray to You. Nuqaddisu laka (We
proclaim Your holiness) means we affirm all Your attributes, and We affirm
that You are pure and free of all impurities and all that the disbelievers
ascribe to You. End quote. 


Tafseer at-Tabari,

But it
is more appropriate to describe the Qur’an as Allah, may He be exalted, has
described it, as He says (interpretation of the meaning):

“These
are the Verses of the Book, and a clear Quran”


[al-Hijr 15:1]


“And indeed, We have bestowed upon you seven of Al-Mathani (the seven
repeatedly recited Verses), (i.e. Soorat Al-Fatiha) and the Grand Quran”


[al-Hijr 15:87]


“(This is) a Book (the Quran) which We have sent down to you, full of
blessings”


[Saad 38:29]


“Ya-Seen. By the Quran, full of wisdom (i.e. full of laws, evidences, and
proofs)”


[Yaa-Seen 36:1-2]


“That (this) is indeed an honourable recital (the Noble Quran)”


[al-Waaqi ‘ah 56:77]


“Nay! This is a Glorious Quran,”


[al-Burooj 85:21]. 

We
should not give the Qur’an the title of “the Holy Qur’an” lest we be like
the Christians who call their distorted and altered book “the Holy Bible”. 

But if
it is asked, is the Qur’an a holy book? We say: Yes, and it is the most
deserving of being called holy and pure, and being described as superior to
all other books. But we do not call it the Holy Book or the Holy Qur’an, so
as not to resemble the Christians in that regard. Even though it may be
described as being holy or pure, it should be given the names that Allah
gave to it and with which He described it, so we should say the clear Qur’an
(Qur’an mubeen), the Qur’an filled with wisdom (Qur’an hakeem),
Noble Qur’an (Qur’an kareem), Glorious Qur’an (Qur’an majeed). 

And
Allah knows best.
