and He said:

‘Do you feel secure that He who is in heaven will not cause the earth to swallow you, whereupon it would quake?’ {16} [al-Mulk 16]”

He cited other verses before going on to say:

“If He were everywhere, He would be inside a person’s belly and mouth, in latrines, and in places one would rather not mention. He would necessarily increase as places increased, whenever He created places that had not existed, and decrease as they decreased, whenever existing places ceased to exist. It would also be valid to direct our appeals to Him toward the earth, behind us, and to our right and left. Yet the Muslims unanimously hold the contrary and deem anyone who says this mistaken.”

Thus, after citing the scriptural texts, he presented three arguments based on rational inference.
