2. Al-Baqara (The Cow)

Surah: 2   Aya: 173

173. Innama harrama AAalaykumu almaytata waalddama walahma alkhinzeeri wama ohilla bihi lighayri Allahi famani idturra ghayra baghin wala AAadin fala ithma AAalayhi inna Allaha ghafoorun raheemun
  

  Translation

173. He has forbidden you only the Maytatah (dead animals), and blood, and the flesh of swine, and that which is slaughtered as a scrifice for others than Allâh (or has been slaughtered for idols, etc., on which Allâh's Name has not been mentioned while slaughtering). But if one is forced by necessity without wilful disobedience nor transgressing due limits, then there is no sin on him. Truly, Allâh is Oft-Forgiving, Most Merciful.
