The Exalted, said: “And He is the Irresistible, (Supreme) above His slaves”. (Al-Anam: 18).
And, the Praiseworthy, said: “And they (all creatures) will appear before Allah, the One, the Irresistible.” (Ibrahim: 48)
The Linguistic Meaning:
Al-Qahr: Dominance, height and also overcoming. God, the Exalted, is the Irresistible and the Subduer: He overpowered all creatures, they surrendered to Him and they acknowledged His Power and Will. He subdued people of the heavens (angels) by service and people of the earth by worship.
The Grandeur of Al-Qaher, Al-Qahharr
He, the Exalted, humbles the tyrants, humiliates the oppressors and terminates the hopes by death. These two Names are so grand that He overwhelms His creatures by gathering them during Doomsday so as to establish justice and truth, God, the Exalted, said: “On the Day when the earth will be changed to another earth and so will be the heavens, and they (all creatures) will appear before Allah, the One, the Irresistible.” (Ibrahim: 48).
