Kalb (term)
The Qur'an strongly enjoins Muslims to treat animals with compassion and not to abuse them. The animals, together with all creatures, are believed to praise God, even if this praise is not expressed in human language.
The Qur'an explicitly allows the eating of the meat of certain halal animals. Although some Sufis have practiced vegetarianism, there has been no serious discourse on the possibility of vegetarian interpretations. Certain animals can be eaten under the condition that they are slaughtered in a specified way. Prohibitions include swine, carrion, and animals dhabihah (ritual slaughter) in the name of someone other than God. The Qur'an also states "eat of that over which the name of God (Arabic: الله Allāh), hath been mentioned".
