The Importance of Respecting the Balance of Nature
"Those who take undue advantage of other species break the Divine Law of equilibrium in nature — and nature never forgives." The Qur'an Majeed dwells on this theme recurrently, such as:
Then a warning is given to those people who are guilty of infraction, in these words:
The Importance of Conserving Nature
Even when the world is coming to an end, "On Doomsday, if any one has a palm-shoot in hand, he should plant it" (Musnad of Ahmad, 5:440 and 3:184, hereafter referred to as Musnad).
There are many Ahadith forbidding blood sports and the use of animals as targets, some of which are as follows:
The Prophet condemned those people who take up anything alive as a mere sport. (Narrated by Abdullah bin 'Omar. Muslim, Vol. 3, Hadith No. 1958)
The fact that these Ahadith repeat the same sayings of the Holy Prophet in slightly varying wordings shows that he took the matter very seriously and repeated them again and again on different occasions in the presence of different people. Another significant point to note in this respect is that, to stop the use of animals as targets or in blood sport, the Holy Prophet did the same as he did in the case of camel-humps and sheep-tails, quoted above. He declared their meat as Mujaththema and unlawful (haram) for consumption, according to the following Hadith:
Military Research, Including Wound Labs
One might also appeal to the Islamic law (Shari'ah) to oppose using animals in military research in general and in the so-called wound laboratories in particular. The above-quoted Ahadith, as well as the Juristic Rules, would seem to support the view that our wars are our own problems and that we have no right to make the animals suffer for them.
Animals in War
Even in war, animals cannot be killed except if needed for food. Hazrat Abu Bakr, the first Caliph after the death of the Holy Prophet Muhammad (632-634 A.C.), addressed the Muslim army at a place outside Medina, called Jorf, before sending them off for the battle of Muta. Among the instructions he gave to the soldiers was not to slaughter animals except for food (Qur'an, 22:40; Tabari III, p. 123).
