Masruq narrates: An udder (cooked meat) was brought to Abdullah bin Mas'ud (may Allah be pleased with him), and a man moved aside and said: "I have made it unlawful for myself." Abdullah (may Allah be pleased with him) said: "O you who believe, do not make unlawful the good things which Allah has made lawful for you" [al-Ma'idah: 87]; feed (the needy) and make expiation.
