Abu Shakir Disani who denied the existence of God told Hisham, a companion of the Imam, “There is a verse in Quran that is according to our belief and which goes against your faith.” Hisham asked, “Which verse is that?” He replied,
And He it is Who is God in the heavens and God in the earth…( Surah Zukhruf 43:84)
This according to him clearly showed that there are different gods for the earth and the heavens. Since Hisham had not pondered on this verse, he remained silent. When he came to Medina, he mentioned it to Imam Ja’far as-Sadiq (a.s) who said, “If he says to you now, you ask him what his name is. He would tell you. Then ask him what his name is in Basra? He would mention the same name. At that time you tell him: Our God is also like that. He is God in the heavens and also God on the earth. He is God in the sea and on the land, in the plains and on the hill.” Hisham did as bidden. Abu Shakir said, “It is not your reply, it has come loaded on the camels from Hijaz.”
