Praying behind someone who believes in Allah's Omnipresence

A: The belief of Ahl-ul-Sunnah wal-Jama`ah (adherents to the Sunnah and the Muslim mainstream) is that Allah (Glorified be He) is high above His Creatures, rising over His Throne and separated from His Creation. Allah (Exalted be He) says, Do you feel secure that He, Who is over the heaven (Allâh), will not cause the earth to sink with you, and then it should quake? He (Exalted be He) also says, Glorify the Name of your Lord, the Most High, He (Exalted be He) also says, And He is the Irresistible, (Supreme) above His slaves The Prophet (peace be upon him) asked a slave girl, "Where is Allah?" She replied, "In the heaven." He (peace be upon him) then said to her master, "Release her, for she is a believer." The Prophet (peace be upon him) used to supplicate to Allah saying, You are the Evident and there is nothing above You. Allah (Exalted be He) also says, Indeed, your Lord is Allâh, Who created the heavens and the earth in Six Days, and then He rose over (Istawâ) the Throne (really in a manner that suits His Majesty). In seven Ayahs in the Qur'an. The Muslims have unanimously agreed that Allah is above His Creatures, (Part No. 2; Page No. 389) rising over His Throne in an unknown way, and His knowledge is everywhere. A person who believes that Allah exists everywhere is a believer in Hulul (a Sufi term meaning indwelling); and it is impermissible to offer Salah behind him, as he is a disbeliever of Allah, His Messenger and the consensus of Muslims.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
