Al-Quddoos
The Most Holy
He is the One Exalted far above any deficiency or defect whatsoever, for He alone possesses the attributes of absolute perfection. This noble name occurs twice in the Qur’an. The first in the verse that reads, (He is Allah, there is no god except Him; the King, the Holy One.) (Sūrat Al-Hashr: 23) And the second is in the verse: (All that is in the heavens and all that is in the earth extols the glory of Allah, the King, the Holy One, the All-Mighty, the All-Wise.) (Sūrat AlJumu‘ah: 1)

In light of this great name, I would say:
1. One of the best means that increases a person’s love for his Lord is knowing His perfection from all aspects and the fact that He has no deficiency whatsoever in His Self or actions.

2. Part of extolling Allah Almighty is to extol His Shariah and deem it exalted above any deficiency. This requires that we rule by nothing except His Shariah and follow nothing but His path, for He alone will ensure our safety in this world and in the Hereafter.

3. A Muslim is recommended, after finishing Witr prayer, to say three times, “Glory be to the King, the Holy One”, raising his voice in the third one. 7

4. One of the good things said about the association between Allah’s name ‘the King’ and His name ‘the Holy One’ is that Allah Almighty is not like the kings in the world who may commit injustice, mistakes, or unwise acts or they go through heedlessness and forgetfulness. He is the Holy King Who is absolutely Perfect and Exalted far above all defects.
