Al-Mutakabbir
Al-Mutakabbir is the supremely great. He is exalted far above all creation. He has rights and privileges and attributes which others do not have. He is truly great and manifests this greatness in all things and in many ways.
From the root k-b-r which in Classical Arabic means:to be great in size, rank or dignity to be great in size, to be vast, formidable to be great in age, oldest to be great in dignity, noble, majestic to be great in learning, most knowing to have rights above all others
He is Allah, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Bestower of Faith, the Overseer, the Exalted in Might, the Compeller, the Superior. Exalted is Allah above whatever they associate with Him. (Quran 59:23)
Abu Huraira reported: The Messenger of Allah (pbuh) said, “Allah the Almighty said: Pride is my cloak and greatness is my garment, so whoever competes with me regarding these two will be thrown into the Hellfire.”
