Salam Aleykom,
Brother Sharif, here is an interesting verse from Isaiah 1:2
Izj 1:2 Hear, O heavens, and give ear, O earth; for the LORD has spoken: "Children have I reared and brought up, but they have rebelled against me.
Notice that in the first loft, heaven and earth are summoned to be a witnesses in the process brought by God to His people. In one of the Hittites's treaties - after a long list of divine witnesses - are mentioned mountains, rivers, the sea, the sky and the earth, and wind and clouds !
This is by the way a case against Christians who says that the oaths - by heaven, earth etc. - in the Quran, has a paganism root (pointing to kahin)
Salam
