Musannaf Ibn Abi Shaybah

Hazrat Qasim, Hazrat Mujahid, Hazrat Salim, Hazrat Ata, and Hazrat Tawus were asked about the ant, locust, and lizard. All the respected personalities said: If one kills them by mistake, there is no harm, but if one kills them intentionally, he should give a handful of food. And Hazrat Amir says: Whether one kills intentionally or by mistake, a handful of food must be given.
