“And he is Al-Qahir (The Irresistible) above His servants. He sends Guardians [writing all of your deeds] over you, until when death approaches one of you. Our Messengers take his soul and they never neglect their duty.” (Sarah Al-Anam:61)
Allah is the One who has subdued everything. The One before whom the whole creation had humbled itself, and submitted before His grandeur, power and strength.
“So think not that Allah will fail to keep His promise to His Messengers. Certainly! Allah is Almighty Owner of Retribution. On the Day when the earth will be changed to another earth and so will the heavens, and they [all creatures] will appear before Allah, the One, Al-Qahhar (The Subduer).” (Surah Ibrahim: 47-48)
