In Islamic law, marriage legalizes sexual intercourse between the husband and wife. Marriage is not restricted to a platonic relationship nor is it only for procreation. Marriage is greatly encouraged in Islam, partially because it provides a lawful institution in which to fulfill oneâs sexual urges.nder Islam, sexual intercourse is regarded as a loving act within marriage and should only be by mutual consent. There is, however, no explicit concept of rape within marriage in Sharia; a wife is deemed to have accepted conjugal relations as part of the marriage contract.
Amphibians are cold-blooded vertebrates. They have a backbone, and they maintain their body temperature through external means, such as laying in the sun. Amphibians spend part of their lives on water and part of their lives on land. They have permeable skin, which gases and some molecules penetrate; they also have gills for some portion of their lives.
Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed.mphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations. They all have four limbs except for the legless caecilians and a few species of salamander with reduced or no limbs.
