Humans have dominion over creation. 'They may rule over all the creatures' (Genesis 1:26)
Allow animal experimentation for medical reasons (e.g. drug / vaccine trials) to ensure the preservation of human life (St Thomas Aquinas - Primary Precept)
Human life is more valuable than animal life (humans are made 'imago dei'). Everything is created for man.
God created animals for Muslims to use as they are beneficial to humans. Use to your advantage.
Allow animal experimentation for medical reasons (e.g. drug / vaccine trials) as humans are at the top of God's creation - they have been given dominion.
