Why Allah uses this name
The Qurʾān names Him at the close of Sūrat , and the enumeration lists as the attribute that phrase carries.
Take this with you
Approach Him with the manners majesty deserves — in your prayer, your recitation and your speech about Him.
'Blessed is the name of your Lord, Owner of Majesty and Honour' (55:78).
Qurʾān 55:78; the name itself listed in Sunan al-Tirmidhī 3507 (the enumeration of the ninety-nine names)
Where it appears in the Qur'an
This name is reported in the list of ninety-nine, but the Qur'an says it as a verb or a phrase rather than as this single word, so there is no word-for-word occurrence to list. The reasoning above cites the āyāt it is taken from.
