Muwatta Malik 1048

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ كَانَ يَقُولُ مَا ذُبِحَ بِهِ إِذَا بَضَعَ فَلاَ بَأْسَ بِهِ إِذَا اضْطُرِرْتَ إِلَيْهِ ‏.‏

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "There is no harm in whatever you slaughter with a cutting edge, as long as you are forced to do it by necessity
