Musannaf Ibn Abi Shaybah

Hazrat Muhammad bin Ali (may Allah be pleased with him), Hazrat Ata, Hazrat Mujahid, and Hazrat Tawus state that if one intentionally kills a locust, an ant, or a lizard, then he should give food in charity, and if he kills it by mistake, then nothing is required of him. And Hazrat Amir and Abdur Rahman bin Al-Aswad state that whether he kills it intentionally or by mistake, giving food in charity is obligatory upon him.
