"... Never will I allow to be lost the work of any of you, whether male or female ..."

Al-e-Imran (The House of Imran) - Chapter 3: Verse 195 (partial)

"... a reward from the presence of Allah and from His presence is the best of rewards."

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]

Abu Said Sad bin Malik bin Sinan al-Khudri (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) said: "harm (darar) may neither be inflicted nor reciprocated." [Ibn Majah]

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.
