How can we conceive of the vastness of Allah's "palm" (kaff) between the shoulders of the Messenger, as mentioned in the Hadith, or its use in the creation of Adam, despite Allah's immense glory and His grasping of the heavens on the Day of Resurrection with His hand?

Allah Almighty has two magnificent Hands, and it is obligatory to believe in them without resemblance or specific modality, as He states: "Rather, both His Hands are extended" (Qur'an 5:64) and "And the whole earth will be in His grasp on the Day of Resurrection, and the heavens rolled up in His right hand" (Qur'an 39:67). And in the Hadith: "Allah, the Mighty and Exalted, will take His heavens and His earths in His two Hands." He also created Adam with His two Hands and accepts charity with His Right Hand. This does not mean that they are like the hands of creation, rather "There is nothing like unto Him, and He is the All-Hearing, the All-Seeing" (Qur'an 42:11). As for the Prophet's (peace be upon him) vision of Allah in a dream, and Allah placing His Palm between his shoulders, it was a dream vision, and it does not mean that Allah's Palm is commensurate with the Prophet's shoulders (peace be upon him). Seeing Allah in a dream is by way of example, not according to reality.
