Quran Sharif, Surat Furqani:. 25, Verse 52, 58-59
It is said in these verses that in reality, Kabir Allah is worthy of being worshipped (Ibaadaii Kabira). This Kabir is that same Purna Parmatma who created the nature in six days and sat on the throne on the seventh day. Ask some ‘Baakhabar’ (one who is fully acquainted with Him) for information about Him.
