Answer
It is not permissible to cause harm to any living creature without a valid
Shar’i excuse. Numerous Ahaadith prohibit cruelty to living creatures, such
as the prohibition of Nabi (Sallallaahu Alayhi Wasallam) that a living
creature be killed (without excuse) while being held in thrall. (Muslim)
and Allah Ta’ala Knows Best
