the final verse of Surah Yā Sīn: “So glory be to Him in Whose Hand is the dominion of all things, and to Him you will be returned.”1.
His words, “and grandeur and majesty,” mean: and the Possessor of grandeur and majesty. These are two closely related attributes belonging exclusively to Allah Most High; no one besides Him is entitled to them. It is authentically reported from the Prophet—may Allah bless him and grant him peace—that Allah—mighty and majestic—said: “Grandeur is My cloak and majesty is My lower garment. Whoever contends with Me over either of them, I shall cast him into the Fire.”2.
Thus, He likened majesty to a lower garment and grandeur to a cloak, indicating that they belong exclusively to the Lord—glory be to Him—and declaring Him far above having any partner in either of them.
Muslim narrated in his Sahīh from Ali ibn Abī Tālib—may Allah be pleased with him—in a lengthy hadith: “When the Messenger of Allah—may Allah bless him and grant him peace—bowed, he said: ‘O Allah, to You I bow, in You I believe, and to You I submit. My hearing, sight, brain, bones, and sinews are humbled before You.’ When he rose, he said: ‘O Allah, our Lord, to You belongs praise filling the heavens, filling the earth, filling all that lies between them, and filling whatever else You will.’ When he prostrated, he said: ‘O Allah, to You I prostrate, in You I believe, and to You I submit. My face has prostrated itself before the One who created and fashioned it and opened its faculties of hearing and sight. Blessed is Allah, the best of creators.’”3.
His words, “O Allah, to You I bow,” place the verb after “to You,” indicating exclusivity; that is, my bowing is for You and for no one else.
His words, “and in You I believe,” mean: I acknowledge and affirm the truth.
