Using animals for medical research
Question

Is it permissable to research on animals for the furthur development of medicine?
Praise be to Allah.We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allah preserve him, who answered as follows:
“I do not see anything wrong with this, because of the general application of the words of Allah (interpretation of the meaning): ‘It is He Who created for you all that is on earth’ [al-Baqarah 2:29]. But it is essential to choose the easiest form of experimentation (that which is least painful to the animals). And Allah knows best.”
