(God ALONE: Note the Reason)
This is because when God ALONE was advocated, you disbelieved, but when others were mentioned beside Him, you believed. Therefore, God’s judgment has been issued; He is the Most High, the Great.
ذٰلِكُم بِأَنَّهُ إِذا دُعِىَ اللَّهُ وَحدَهُ كَفَرتُم وَإِن يُشرَك بِهِ تُؤمِنوا فَالحُكمُ لِلَّهِ العَلِىِّ الكَبيرِ
zaalikum bi annahooo izaa du’iyal laahu wahdahoo kafartum wa iny yushrak bihee tu’minoo; falhukmu lillaahil ‘Aliyyil Kabeer
*40:11-12 The disbelievers go through two deaths, while the righteous believers do not taste death, beyond the death we already experienced (44:56). Please see Appendix 17. The reason for going to Hell is obvious; even those who believe in God associate others with Him (see 39:45).
