He has only forbidden for you what is already dead, the blood, the meat of pig, and what was dedicated to other than God. Whoever finds himself forced out of need and without disobedience or animosity, there is no sin upon him. God is Forgiving, Compassionate.
Translation endnotes
[2:172-173] Throughout the Quran, only four dietary articles are prohibited (6:145; 16:115). Other dietary prohibitions are the products of those who have divided themselves into sects and factions by following hadith and sunna. Prohibiting something that God has not prohibited in the name of God is another way of associating partners with God (6:121,147).
