“Their sides forsake their beds as they call upon their Lord in fear and hope” ⦗al-Sajda: 16⦘.
He, Exalted be He, also said: “Those who remember Allah while standing, sitting, and lying on their sides” ⦗Āl ʿImrān: 191⦘.
The Prophet—peace and blessings be upon him—said to ʿImrān ibn Ḥuṣayn: “Pray standing; if you are unable, then sitting; and if you are unable, then on your side.”
Should it be assumed that the annexation here actually entails an attribute of Allah, the discussion is governed by the same principles that apply to every other attribute ascribed to Him; and in the Torah there are passages parallel to what the Quran contains on this point.
This becomes even clearer through the third approach: namely, to observe that the descriptions of Allah found in the Quran and in the hadith of the Prophet—peace and blessings be upon him—regarding these attributes, which some people label “anthropomorphism,” are identical to what is found in the Torah and the other scriptures of the prophets, and that what appears in the Torah and those prophetic writings is not something later fabricated by the People of the Book.
