What is the meaning of Allaah's name al-Quddoos (the Holy)?
Praise be to Allaah.
Al-Quddoos (the Holy) is the One Who is Blessed and Pure, who is
exaltedabove all impurity. It was said that the angels sanctify Him
and He, mayHe be exalted, is the One Who is praised for His virtues
and goodness.
Allaah is al-Quddoos because He is far above having any opposites,
rivals, partner or son. He is described as being perfect, and is far
above having any faults or shortcomings at all. He isfar above
anything being near Him or like Him in any aspect of His perfection.
Ibn Jareer said:
"Taqdees (sanctification)is purification and veneration… Quddoos…
purity and veneration are for Him, hence land may be described as ard
muqaddasah or holy land, meaning that it is pure. When the angels say
'Nuqaddisu laka (we sanctify You)' it means we attribute to You
Yourattributes of being pure and free of all impuritiesand of all that
the people of kufr attribute to You. It was said that the angels'
sanctificationof their Lord is their prayer (salaah). Then he
mentioned some of the comments of the mufassireen, who said that
taqdees (sanctification) may mean prayer, veneration,
glorification,magnification or obedience. Salaah and veneration come
back topurification because they declare Him to be pure and free from
all that the people of kufr attribute to Him.
Ibn al-Qayyim said:
One of His attributes is the Holy, declaring Him to be above all
imperfection and glorifying the Most Merciful
