Ali Ibn Abi Talib reported, "When I took possession of the weapon of the Messenger of Allah, peace be upon him, I found in the hilt of the sword a parchment saying, 'Keep relations with those who cut you off, behave well towards those who treat you badly, and speak the truth even if it is against yourself.'" [As-Saheehah of Abu Amr Ibnus Sammak]

Al-Baqara (The Cow) Sura 2: Verse 29

"It is He who has created for you all that is on earth, and has dealt with the heavens formed appropriately into seven, and He alone has full knowledge of everything."

Although the above verse is dealing with the creation of the whole universe and the multiple cosmic systems indicated as "heavens" be they within or beyond the human perception, it states significantly an essential general law: that God "has created for you all that is on earth". Consequently, as our jurists since early times rightfully inferred, everything on earth is pure and allowed to be used, unless it comes to be clearly forbidden by God.

Al-Saffat (Those Ranged in Ranks) - Chapter 37: Verse 164

"There is none among us, but that he has a known station."

These are understood to be the words of the angels, each of whom is assigned a station that is never left; some remain bowing, never straightening their spines; others remain prostrating, never lifting their heads. In the immediate context, this verse is a declaration that they, like the jinn, know that any worship of them is misplaced. More broadly speaking, that all angels have a known station indicates that they have, like all created things other than human beings and jinn, no freedom to move from one station or level of being to another.
