No harm is one of the four bioethics principles that sometimes it and beneficence are defined as one principle. This principle, beside other bioethics principles, is used as an ethics code in modern biotechnologies especially in new achievements in medicine.
This principle states that use of modern biotechnologies should not harm to any person even the nature and animals. This principle has a long history in Islam so that we can say it is contemporaneous with it.
In Islam it is called la-zarar act that governs all of Jurisprudence as a universal act.
Since the jurisprudence supervises on all of interactions and personal and social relationships, naturally it involves this ethical principle that is related to human behavior wit himself / herself and with other congeners.
