Allah, the Exalted, said (in Surah An-Nisa) «اليوم أحل لكم الطيبات وطعام الذين أوتوا الكتاب حل لكم وطعامكم حل لهم‏» : "This day all good things have been made lawful for you. The food of those who were given the Scripture is lawful for you, and your food is lawful for them." Az-Zuhri said that there is no harm in the slaughtered animal of the Christian Arabs, and if you hear that they mention a name other than Allah at the time of slaughter, then do not eat it, but if you do not hear (anything), then Allah has made it lawful for you, and Allah knew of their disbelief. A narration similar to this is also reported from Ali (may Allah be pleased with him). Hasan and Ibrahim said that there is no harm in the slaughtered animal of the uncircumcised (People of the Book).

Narrates `Abdullah bin Mughaffal: While we were besieging the castle of Khaibar, Somebody threw a skin full of fat and I went ahead to take it, but on looking behind, I saw the Prophet and I felt shy in his presence (and did not take it).
