Musannaf Ibn Abi Shaybah

Hazrat Mujahid says that sometimes an ant bites my stomach, so I catch its head and crush it, and its remaining part stays on my stomach.

Hazrat Ata was asked about a person who killed many ants but does not know their number. He replied that he should give many dates in charity.

Hazrat Saeed bin Jubair was asked: What if a person in the state of Ihram kills a large number of ants? He replied: He should give charity.

Hazrat Tawus was asked, "I put on the Ihram and then killed many ants?" He replied, "Give a few handfuls of wheat as charity."

Hazrat Ata was asked: What if a Muhrim kills an ant? He replied: He should give some food in charity.

Hazrat Tawus was asked, "What is the ruling on killing an ant in the Haram?" He replied, "If it causes you harm, then there is no problem."

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.
